5.0 out of 5 stars Pretty Neat 3D Pen, April 30, 2015
One of the coolest technology developments in the recent years is the sudden accessibility and proliferation of the 3D printing technology. 3D printers have come down in price a lot, but they are still just outside the reach of most small hobbyists and maker enthusiasts. Furthermore, there is a pretty significant barrier to entry in terms of the ability to use 3D printers right “out of the box” for your own small scale projects. You need to learn about modeling your objects in some sort of CAD/modeling software which can be tricky. Furthermore, 3D printers can still be tricky to operate, even the most user-friendly ones. So if you want to find out what 3D printing is all about without investing too much time and money and learning all the necessary skills, then a small and convenient 3D “printing” pen like this one can come in handy.

This 3D pen is in a way a modified glue gun. This means it uses high heat to soften and melt the plastic filament which can be applied in a way that creates an interesting two dimensional or three dimensional pattern. However, since the pen can get pretty hot you really want to be careful when using it. You could easily get burned, or even start a small fire. I recommend getting a little support stand for this pen before you start doodling.

3D doodling is not too hard, at least not after you get used to it. Getting elaborate 2D patterns is pretty straightforward, but getting into the third dimension can be very, very tricky, especially if you do it by hand. If you really want to make cool three dimensional objects I suggest that you build them up from two dimensional pieces that you “glue” together with this pen. There are many nice patterns available on the web for this, and I made a decent little replica of the Eiffel tower this way. (See some of the included pictures.)

The pen comes with four different colored filaments, about a couple of meters in length for each. That seems a lot, but I quickly ran out of material after just a couple of little projects. I didn’t see any info on what kind of material these filaments are made out of, but I guessed that it’s the ABS plastic, one of the standard 3D printing materials. I have a lot of extra of this stuff laying around, and I tried to use one of the spools with this pen, and it worked like a charm.

One of the issues that I have with this pen is that the filament deployment speed can’t be adjusted very precisely. I ended up primarily using the higher speed, but at that speed you really need to be very skillful to apply it well.

Overall, I really enjoyed playing with this pen. It’s a cool gadget that will nicely introduce you to the world of 3D printing. It’s primarily intended for hobbyists, and I would not recommend making any “serious” stuff with it. However, as an art tool it’s one of the coolest little gadgets that I have ever used. Highly recommended.

5.0 out of 5 stars Excellent Car Diagnostic Tool, April 30, 2015
This is a very well made, effective and convenient car diagnostic tool. I've used it on my Honda Civic and Honda CR-V and it provided me with a lots of useful information on these vehicles. It was particularly useful with my older Honda Civic, which has been having some issues for a while.

The reader is very straightforward to use and read. It comes with a small instruction manual, but most of the stuff was pretty self explanatory.

The reader seems pretty well built. It feels like a product that will last me a while.

This is a very convenient and well designed epilator. It is compact and easy to use. It is very comfortable, as long as you warm up your skin before the use. It removes hair very thoroughly and efficiently. Nothing beats waxing, but this epilator comes pretty close. It is alow pretty easy to clean and maintain. It seems durable and likely to last a while. Recommended.

5.0 out of 5 stars Good Desk Lamp, April 30, 2015
Since most of my work is done at the desk, I am a big user of desk lights. Until now I was a big fan of halogen lights since they gave me the most intense and concentrated light. However, they have a whole host of issues: they get really hot, and their light bulbs tend to be really hard to replace. Since the LED lighting has come a long way in recent years, I was ready to try it out with my desk lights. So far I have been pretty impressed. Here are some of my impressions of this Jebsens desk lamp.

**** Pros ****

– Decent amount of light. I have completely replaced my old halogen desk lamp with this one. Works fine for my main purpose while at my work desk – writing reviews such as this one.

– Neat and elegant design. The lamp looks very contemporary and stylish. Fits well in most modern office environments.

– Convenient dimmer provides for very easily adjustable brightness. I usually like my desk lamps to be as bright as possible, so this feature is not a major plus for me, but I can see how it would be helpful for many others.

– No major source of heat. LED lights are very cool to operate.

– Reasonable price. Since the LED lights use much less power than the conventional lightbulbs, they are much cheaper to operate. This desk light could easily pay for itself after a few months to a year of operation.

– Sturdy build. This is one of the sturdier LED desk lamps that I’ve come across.

**** Cons ****

– The LED light quality can feel a bit cold and uninviting. This is not a major issue for me for desk lights, but in general I prefer light bulbs with much more “warm” look and feel.

Overall I am really happy with this lamp and would warmly recommend it.

5.0 out of 5 stars Well Made Women's Messenger Bag, April 30, 2015
This is probably the most luxurious and finely made messenger bag that I have come across. It combines elements of classical professional design with a very modern and functional look. Its soft leather design is equally at place in a C-suite meeting and a tech startup cubicle. Thanks to the included removable strap it can double as a messenger bag, and be used for your daily work commute.

The bag is made out of high quality leather and it feels exquisitely well made. It is the kind of bag that has a potential to last you a lifetime. It is easy to open and close, and its soft leather handles sit very comfortably in your hand.

The bag features very nicely done compartmentalized interior. There is a big padded compartment for a laptop, as well as numerous small pockets for accessories. The bag is an ideal accessory for someone who carries a lot of different computers, tablets, gadgets, cameras and other small accessories, in addition to papers, notebooks and other more traditional carry-on items. The only “problem” with this kind of high functionality is that it subtly encourages overpacking – this is one of the issues that I constantly struggle with.

The bag is overall very well padded and will likely protect your gear and other valuables from small inadvertent bumps and scratches. However, this is not a hard-shell bag so I would be very careful to avoid hard impacts. I would certainly not feel comfortable carrying this bag with me on a daily biking commute – chances of serious impact could be considerable that way.

This is one seriously good looking and functional bag. Highly recommended.

5.0 out of 5 stars Excellent Gaming Headphones, April 30, 2015
If you are a serious gamer, then you value having dedicated gaming-only headphones at your disposal. The Afunta Sades headset is one of the better headsets in that category that I’ve tested. I would strongly recommend them to all but the most discerning gamer/audiophiles. They were pretty impressive in almost every category that I could think of.

**** Fit and Comfort ****

The headphones are fairly large and will fit most ear sizes. They are very soft and comfortable, and they will not start hurting your ears after several hours worth of use. They will also keep their shape, which is a good thing and something that is not a given for all other headphones that I’ve used over the years. The only discomfort that you may experience will be due to the heating of your ears. This may not be a problem if you live in a fairly cold place to begin with, but in the summer this could become an issue.

**** Design ****

The headphones look very modern and stylish. The blue color is quite noticeable, and it distinguishes these headphones from the regular audio headphones without making them look dorky.

**** Microphone ****

The retractable microphone is a very clever design feature. When fully tucked in the microphone is almost completely invisible, which is a great thing when you are either playing a video game on your own, or are in mood for music. Microphone’s flexible handle also insures that you can position it to precisely suit your needs.

**** Sound Quality ****

The sound coming out of these headphones is very impressive, although not quite at the level of dedicated stand-alone audio-only headphones. Nonetheless, I’ve been using these headphones with my iPhone and overall I am pretty happy with the kind of audio experience that they provide.

**** Noise Cancellation ****

These headphones use the passive noise-cancelling technology, which means that they solely rely on their shape and build to prevent outside noise from reaching you. The passive noise cancellation is not nearly as effective as the active kind, but for the purposes of these headphones that might be a good thing. This is because in my experience the active noise cancelling headphones also cancel your own voice to some extent, which makes talking extremely weird. So for the gaming headphones you would probably want to be able to hear yourself as clearly as possible.

**** Conclusion ****

If you are looking for a solid, serious full-size gaming headset then you don’t have to look any further. This headset will be more than adequate for all of your gaming needs.

4.0 out of 5 stars Good Geadphones, April 30, 2015
These days I listen to music on my iPhone primarily in the gym while exercising, and for those purposes the Bluetooth wireless headphones are mostly adequate. However, almost all of those headphones have very subprime sound quality, to say the least. The standard iPhone headphones are not much better, but they are usually the ones that I reach for when listening to music in other situations. Unfortunately, as a consequence of these choices of headphones I’ve been inadvertently forced to settle for a rather inferior music-listening experience. So when I came across Soundsoul headphones, I felt that my ears had been opened. I’ve used high-quality headphones in the past, and in terms of sound quality the Soundsoul headphones are definitely on par with many of those.

***** The Sound Quality *****

The sound quality is definitely one of the biggest selling points of these headphones. They make a crisp, loud and well-formed sound. When listening to classical piano works I can hear each note reverberating clearly and distinctly from the others. The high notes don’t have the “tinny” sound that I’ve been accustomed to from many lower-end headphones. The lower notes are rich and warm, and the headphones can handle the bass sounds as well as any in this category that I’ve tried. The high fidelity of sound is particularly noticeable when listening to the older recordings – all the subtle “noise” of such recordings comes clearly through. The wooden build of these headphones probably have a lot to do with the particular quality of their sound.

***** Noise Canceling *****

These headphones don’t have the active noise-canceling capabilities, but their passive noise suppression and “noise isolation” were more than adequate for most of my purposes. This is particularly the case when listening to music somewhat loudly – all the surrounding sounds were completely blocked, and hardly any of the headphones’ own sound leaked out.

***** Look and Feel *****

These headphones look pretty elegant and fashionable. The metallic look definitely sets them apart. I also like that the playback/volume controls are placed directly on the cable. The headphones are very light and they fit smoothly and unobtrusively into your ears. Even after a few hours of listening to the music on them they did not become uncomfortable. Oftentimes I have a slight pain in my ears after wearing some other in-ear headphones, but so far I have not had any such experience with Soundsoul headphones.

***** Conclusion *****

These are really good headphones and they will make most music lovers happy. They are solidly built and have pretty good sound quality. They are not the highest quality headphones you’ll come across, but they definitely get the job done. Recommended.

4.0 out of 5 stars Decent Headset, April 30, 2015
I am not a big fan of bluetooth headsets for telephony, but this is one of the better designed and convenient headsets that I’ve come across. The headset was easy to pair up with my iPhone 6 plus. The controls are well made, but they are not the most accessible controls around. This is probably due in no small measure to the fact that this headset is fairly small. Its size, however, is overall a plus – the headset is very lightweight and comfortable. The soft rubberized earpieces also greatly contribute to the overall comfort level. The in-ear soft clip keeps the headset firmly in place, and even with some jerky head action it did not fall off.

The overall signal quality for this headset was indeed pretty good. The sound is still not as clear and sharp as with a wired headset, but I was able to have numerous conversations with it without any serious side effects. The best of all, people on the other side of the line did not have any issues either.

5.0 out of 5 stars Very Capable Audio Recorder, April 29, 2015
I have used several dedicated voice recorders, including the very sophisticated and capable Sony recorder. That one works really well, and I am overall very pleased with it. However, it costs much more than this aLLreli recorder and it doesn’t come with as many functions/accessories.

The quality of audio recordings that this recorder provides is very good. It can even be used for music recording, albeit with some caveats - you will not want that recording to be used for a professionally released music tracks. However, for audio recording this gadget really works exceptionally well. The recorded voice is very crisp and clear, without sounding muddy or distorted. The 360 degrees microphones were capable to pickup voices from several different directions without losing any clarity. This is particularly useful if you are recording meetings or interviews, with several different people in various locations around the room. The separate external microphone also comes in handy.

The 8 GB internal memory is more than sufficient for many hours of voice recording.

This is not the best built recorder, nor do the accessories feel all that great. It’s a fairly cheaply built device, and I am not certain how much mileage you will get out of it. I’ve used it for a few days, and so far it has worked alright, but it’s too early to tell if that will hold in the long haul.

This is a pretty well built recorder, that seems professional and durable. It's definitely at least as capable as some other recorders in this category from better known companies. Highly recommended.

4.0 out of 5 stars Good Clip-on LED Light, April 29, 2015
LED lights have really revolutionized lighting. They are small, use up very little energy, and don’t become hot. They have been used in flashlights for quite a while, and now they are slowly but surely moving into all the lighting fixtures in our homes. Thanks to their unique features they have many advantages over the incandescent and halogen lights, and can be used for purposes and situations that go well beyond what the traditional lighting was designed to cover. The case in point is Kedsum clamp-on desk lamp. It is a well designed desk lamp that can be used in a variety of situations and arrangements.

This lamp gives off a decent amount of light. There are three different levels of lighting. I have completely replaced my old halogen desk lamp with this one. Works fine for my main purpose while at my work desk – writing reviews such as this one.

The lamp looks very contemporary and stylish. It fits well in most modern office environments. The clamp base also ensures that it can be placed in a variety of places. I sometimes attach it to a book case while reading in my main living room. the clamp is sturdy and will keep the light in place for a while. The flexible neck also ensures that you can adjust the angle of the lighting in a practically infinite number of way.

This light operates at the 5000 K temperature spectrum. This is as close to the peak daylight spectrum as you’ll come. It makes this lamp give off a very clear, white light. This is an ideal light, if you ask me, for reading and writing purposes, as well as showcasing objects in your home. It’s also the kind of light that photographers use in their studios, as it really accentuates the colors of the photographed objects. This could be a good light to have if you are for instance photographing small objects. However, this type of light is not ideal for accent lighting purposes. The light is too sterile and cool looking, and evokes a hospital or some other similar unwelcoming settings.

This is a truly unique and effective light that will be right at place in most modern homes. It’s functional and beautifully designed, and for what it offers very affordable. Highly recommended.
