As a home schooler, I am always collecting bits of technology to implement the learning curve of the bright little minds. This scope perfectly overcomes the limitations caused when your students have glasses or sight problems. They can gather around it and turn the LCD to share discoveries.
The build quality is satisfactory, every function works as described. Some reviews claimed to see dark spots on the screen. I found nothing of the sort. There were some dark bubbles in the thin plastic film which was screen protection in shipping. Maybe they didn't know to remove the plastic film? As with any lab tool you have to keep the lenses and slide environment very clean.
Gripes: The largest magnifier has to get VERY close to the slide to magnify contents. This means that the light from the top LED gets obscured. This somewhat limits the ultra magnification to things like thinned liquids or transparent objects that can be back lit. Other scopes have a moving stage area instead of little metal arms that this one has to move the slides around. The movement left and right or front to back of the slides is not very fluid and feels like cheap plastic bushings or something.
Likes: The carry case is well made with a shoulder strap. The seven included slides provide good contrasts of color and sample variety. I will be purchasing more along with some blanks. We were able to identify and view individual blood cells, bacterium, plant cells and the like. With some practice we got scary up-close with a sugar ant. In the LCD Deluxe Digital Microscope, Celestron has nailed a good balance of features to educational value.

I've had one for 6 days and it's great for 40x to 600x views of the pond scum from buckets in my yard. I've seen and video'd cloning of verticella. Also saw rotifers, paramecia, and lots more. The video files are saved as .avi files, and can be edited with both PC and Mac editing programs. The scope is Plug n Play with both my Windows 7 64-bit, and my Mac Snow Leopard. I can easily edit videos with my Sony Vegas Suite. Mac Final Cut Express required an extra step of rendering before it could be edited, about as long as the original .avi clip.
In other words, this is a very flexible piece of hardware for education/entertainment.
The only flaw I've found is the lack of info about the microscope stage.
My personal very rough measurements are:
At 40x, the width of the field is roughly [est. eyeball +/- 10% ???] 1.5mm or 1,500 microns. That would translate with other objectives, to
40x screen width 1,500 microns
100x screen width 600 microns
200x screen width 300 microns
400x screen width 150 microns
600x screen width 100 microns
Other rough estimates: [Micrometers = microns]
One turn of the vertical knob is about 20mm/20,000 micrometers.
One turn of the horizontal knob is about 3mm/3000 micrometers.
So you can probably use those dimensions to guess actual size of microorganisms when measured with Photoshop or others.
My rating is a 5 for hardware and software. It loses a full point for absence of info on measurements. I did them myself, but take them with a grain of salt. Celestron should add these specs to theirs.

I agree with J.D.P's review with one exception: J.D. did not mention that the upper light does not illuminate the key spot on the slide under the lens. The slide mechanical stage and the lens's obstruct the light beam casting a shadow over the viewing area. It works somewhat with the smallest (4X) lens but not with the other 4 lens's. In my opinion this is a serious design flaw. I am attempting to return the unit. The upper light is required for proper lighting in many cases.

I did not purchase my Celestron 44345 microscope from Amazon but I thought I'd post a tip here for those considering this item. I originally purchased this microscope from Costco dot com. They had a great price but the scope had several problems: 1) the lower light flickered (apparently a common problem with Celestron microscopes) and that affected the LCD display, 2) the LCD display had problems with red, so that viewing red items caused pixels in the display to flicker, and 3) the stylus for the touchscreen was broken. I contacted Celestron and they advised to return the scope for a replacement. The feature set for this microscope is pretty unique and I wanted to find a replacement that worked, but based on the feedback here on Amazon regarding the regular (non-deluxe) version of the Celestron LCD microscope I was reluctant to order another sight-unseen because the flickering illumination issue seems to have affected quite a few. Unfortunately, I am in a state that does not have any Celestron microscope dealers where I could have inspected a scope, but I was able to contact a dealer in Oceanside CA who graciously tested one out to ensure it did not have any issues. It's a beautiful device and I am glad to have it. So, the tip is simply to consider a similar strategy if this scope interests you -- find a seller who will check it out. BTW, one of the included slides is an apple and that works well for the "red" test.

I got this microscope to use as a tool for my homeschooled daughter. It is a great learning tool. I have not had any problems with it (as indicated by other reviewers for a different model.)
It is nice to be able to view slides with my daughter as she is studying them. The pictures the camera produces are wonderful.
The traditional features of the microscope are good - lighting, stage movement, filters, lens. Even my husband, who is a pathologist and looks through a microscope everyday of his life is impressed with this one!
This is a fine, modern microscope for the proce.

I purchased this microscope for my son's 11th birthday 9we are home schooling him) While I was not expecting a laboratory grade instrument for 250$, I would at LEAST like it to do what ot said it would in the description! the only things on it that worked were the 2 illumination lamps. The LCD screen was either black or white...no touch-screen...nothing. I had to call the company 7 (SEVEN)! times to get them to replace it with a new one. Every time I tried to access technical support,they had a recording saying they were closed (i was within their buisness hours). When I recieve the replacement scope,I will write another review,wether it works or not. This may be the last Celestron product I ever buy.

I received my Pentaview and could not get it to power on using the adapter. Batteries were ok. I traced the problem to the adapter itself (it wasn't producing any output), and requested service/replacement using Celestron's customer service site. It took them TEN full days, just to respond to the initial report. Naturally that first response was unhelpful (did you check the plug, did you have the SD card inserted, go read our faqs, bla bla bla). I'm an engineer. They finally agreed to service it (three weeks after my initial request), but insisted on me shipping the entire microscope back. Since I had every reason to assume that it would be months in their outrageously under-staffed service department, if I ever saw it again, I decided to go find a replacement adapter myself.
Three things were very telling: (1) Their support site is full of questions about adapter specifications! (2) There are numerous review sites warning about Celestron customer service, and (3) They marked my issue "closed" after their very first response, in spite of the fact that I had a non-functional microscope for two months, that was only finally fixed WITHOUT their help and in spite of their appalling service.
I wanted to like it! It's a great concept, being able to share the view, hooking it up to a big screen, taking pictures. Brilliant ideas. But wow, I wouldn't pay for anything from Celestron again. You might get lucky, but all signs point to serious quality issues, an utterly overwhelmed and undertrained staff, and an unenlightened process. Oh, and 4 out of 10 visits to their service site, it was down. Beware.

We just received this unit and it never worked. Called Celestron and they think that the LCD is not working and that we should return it. So back in the box it goes. Also, there seems to be a little wear on the bottom of this unit that would indicate that it was previously returned or sat on a retail shelf for some time. Either way, it was marketed as new not 'like new' or 'previously owned' or even refurbished.
Fortunately we ordered well ahead of our son's birthday so we have time to come up with something else. Also, Amazon's return process is really quick and easy. We'll have to see how long it takes to get our refund.
I am still excited about this microscope as a fun educational tool with a lot of flexibility, but haven't gotten a chance to see it in action yet. If you're on the fence about getting this just make sure that you leave enough time for a backup plan in case it does not work.

ive had two of the Celestron LCD Deluxe Microscopes. the first one was returned because just out box i turned LCD monitor on and could not turn off. so i had to unplug the device, which would not turn back on. so i returned for replacement. now ive just received replacement model and the touch screen does not respond on this one regardless of suggested methods of resetting the machine. so, obviously this is a poor design. hopefully i can return for refund and use for less expensive higher quality microscope camera, notice the resolution on the Celestron LCD Microscope is rather low and can not be interchanged nor replaced.

The first one I ordered was actually new but was faulty it had a software problem and locked up when trying to view images taken and stored in it's internal memory after which no further functions were possible. This unit was returned the same day. Amazon despatched a replacement the same day which arrived here this afternoon.
The replacement Item described as new was a used item. It had a user added screen protector, a plastic washer loose in microscope bag which may belong somewhere on this microscope? , paint chip on slide positioning rail, Sample slide left in microscope, sample slides open and handled. The Celestron printed box should be as from manufacture enclosed in an outer box of cardboard with a Celestron barcode on and the security tabs were missing from the printed box. Therefore the microscope was not even in its original packaging. I have no idea as to whether this item has any other faults as it was totally unacceptable as a replacement for me to proceed any further other than returning it straight to the box in the same condition as it was delivered. The user manual was folded at the base of the box and not in pristine condition as it would have been if it had been laid flat against the sides of the box.
Note: I will be returning this microscope today to Amazon in exactly the same condition that it arrived with me.
My experience of Amazon is shattered this is not the first time that I have received items recently from Amazon where the item described as new has been a used item.
I will expect in all fairness some form of monetary compensation as a result of Amazons failures in this matter. I also expect a prompt replacement a brand new item in correct packaging with security tabs intact. Amazon you really do need a shakeup regarding the handling and distribution of products to ensure customers who buy new get new.
