Top Customer Reviews	BlueProton USB 2.0 By K F on June 15, 2011 Verified Purchase I love this little gadget. Couldn't live without it. My first one lasted for years, until I spilled coffee on it. I ordered two so I could have a back up. I wrote on my Facebook: What? You can't upload photos cause you can't find your camera cord? Well for $7.90 (includes shipping) you can order 2 Blueprotons from Amazon.com. You just insert your memory card into the do-hickey and plug it in a USB. Voila' No more excuses. You know who I'm talking to. Mine just bit the dust and I ordered two. So inexpensive. Meanwhile I put chip into an old mp3 player and plugged it in. Worked. Sort of. Read more Read more	Not what I was expecting. By Linda McLinda on January 16, 2014 Verified Purchase I was looking for a mini SD card adapter, because I have so many mini-SD cards and only my phone to use as the adapter. This is a REGULAR SD card reader, In other words, you still have to have the regular sized SD card adapter for your mini in order to use this. So what's the point? My laptop has a built-in SD card reader! And why does it say 6-in-1??? It has one slot, for a standard SD card! That's it. And the material itself is cheap, not like I'll be wearing it out though as it's completely useless to me. Read more Read more	Makes my fastest cards run 50% faster - even from an USB 2.0 port By NLee the Engineer on May 8, 2013 Color: Black Verified Purchase I have been using several USB 2.0 card readers in the past, including the [[ASIN:B0011EAYO6 Transcend M5 Multi-Card Reader]] and [[ASIN:B002PX99D4 Sandisk Mobilemate SD Plus Memory Card Reader]]. With memory cards getting faster over the years, I started to get the feeling that my old card readers are limiting the Read/Write speed of my newer memory cards. That's why I purchased this [[ASIN:B009D79VH4 Transcend Information USB 3.0 Card Reader (TS-RDF5K)]] just to try it out, even through all my computers only have USB 2.0 ports. Upon arrival of the RDF5, I benchmarked over one dozen of my SDHC and microSDHC memory cards, with speed rating from class-4 to class-10 and UHS-1. The program I used is called "CrystalDiskMark v3.01 x64". It reports, among other things, sequential READ and WRITE speed of memory cards. To my surprise, several of my fastest cards showed about 50% improvement in Read/Write speed compared to when using the old M5 card reader. As an example: for the [[ASIN:B007X7U224 HP CG790A-AZ 32 GB Flash Memory Card Class 10 SDHC]] I was previously getting 19.6MB/s in Write and 20.1MB/s in Read. But when used with the RDF5, its throughput jumped 50% to 29.7 and 34.8MB/s, respectively. The [[ASIN:B008CVHLT2 Transcend 32 GB Class 10 UHS Flash Memory Card TS32GSDHC10U1E]] also shows nearly identical improvement. The above proves that using old card reader was the bottleneck for my fastest cards. On the other hand, improvements for my slower cards were less noticeable, typically around 5% or less. That include [[ASIN:B004TS1IG4 Kingston class-4 SD10G2/16GB]], [[ASIN:B001ECQVTM Transcend Class 6 TS16GSDHC6E]], etc. See the summary of benchmark results I uploaded to 'Customer Images' section for details. The only negative about this RDF5 card reader is that: it does not allow simultaneous usage of both SDHC and microSDHC slots. That is, you can only insert one card at a time, but never both. Conclusion: I am very happy with the dramatic improvement I can achieve with this card reader, even when it is connected to an USB 2.0 port. Once I upgrade to a new computer with USB 3.0 ports, I expect the benchmark results to be even better - at least for my fastest cards. In the mean time, I consider this card reader the cheapest computer upgrade I can recommend. [Update on Dec 26, 2013] I finally have a computer with USB 3.0 port, so I re-tested ~10 memory cards to see the difference. - For any card marketed as 'UHS-1', I observed huge improvements in both Read and Write speeds. - For any card marketed as 'class 10' but not UHS, I may see some increase in Read, but very little difference in Wrire. Bottom Line: If you have an UHS-1 card, make sure to use the RDF5 card reader in conjunction with USB 3.0 port, in order to get the full benefit. Read more Read more	Ruined two chips, reformats to code in computer REad all the bad reviews before you buy By S. da Rosa on September 1, 2010 Verified Purchase NOTE: I would give this a ZERO STAR RATING if I could This chip worked 4 times. I was using a 16gb scandisk SD card. On the 5th time, using the USB extension it opened to a folder on the desktop which was all in code. Then it flashed the message that it was removed improperly which could cause problems etc.. except I had not removed it. I ejected it and put it in without the usb extension and it said memory card could not be read. I put the chip back in my camera and it said the same thing and would not allow me to reformat it. It made the card unreadable to any reader OR my camera and I lost all photos and cannot reformat the card, which is basically now lost. I put a new 2gb chip in my camera, took some photos. It downloaded them twice. The third time it did the same thing as above, ruined another chip. Two unusable chips later, I have thrown this out and will buy a more expensive reader with five stars.

Better read the fine print on shipping charges, $3.99 each.

ByAmazon Customeron February 27, 2010

Verified Purchase

This looked like a good product, so I ordered three. I thought that would make up for the high shipping & handling charge of $3.99. When they arrived, shipped in a small envelope, 4 oz. first class, costing them a whopping $1.39, they had charged me $3.99 each for a total shipping-handling charge of $11.97. To top that off, out of the three, only two worked. Want to get ripped off for junk and robbed for shipping, buy from Amazon and BlueProton. Amazon shows you an invoice before you push the final purchase button and even emails you one. Does it show shipping charges? Not way.

Reads everything except the memory stick and SDmicro chips.

ByKentucky Grandmaon January 27, 2014

Verified Purchase

I have used this reader extensively for several years and it has held up and done an excellent job. I knew its limitations when I bought it but it is exactly what I needed and what was advertised. Great and well priced answer to my needs.

BlueProton USB 2.0 Mini Card Reader

ByMHon March 18, 2011

Verified Purchase

I needed a device to read my SDHC card. I wasn't sure how well this card reader would work since I had never seen the model or brand before, but for the price I thought it would be worth a try. It works well so far, reading my SDHC card, downloading files and being able to sort and delete them. I'm satisfied with this purchase.

trashed my microsd card

ByJDSon December 6, 2013

Verified Purchase

I'm pretty sure this junky item trashed my microsd card. The card was fine. I put it in this reader. The card came out corrupted. It could have been something else but this reader was the last thing the card was used in.

Great Product

ByMCon October 30, 2008

Verified Purchase

I have been using this reader/writer for several months, and it works perfectly with my SDHC memory.

I have it connected to a USB 2 interface and the file transfers are very fast. The speed limitation is due to the class of memory, and I can see a big difference between my class 4 and class 6 memory sticks.

You can spend a lot more money on a reader/writer, but none will work any better.
