SanDiskSDDR-121-A11M MobileMate Micro Memory Card Reader (Red/Black)

The unit that I received is the genuine SanDisk item. Even after having read about the unit's minuscule size, I was still very surprised by it's very small proportions. The item's construction is also as light duty as has been mentioned in other reviews. My only caution about the construction of this unit is that the plastic case is thin enough to be crushed easily by a heavy item in one's case or book bag. On the postitive side, although my first two attempts at downloading files from my smart phone's memory card to my PC failed (HTC to Sony Vaio), the third attempt worked perfectly and the download speed was very impressive. My best guess to explain my first two failures is that I may not have pushed the card into the reader far enough. Because the price of the item is negligible, and it worked so well and quickly at downloading my pictures and videos to my computer, I can fully recommend this item. If after inserting the loaded card reader into a USB port of your computer the instructions for finding your downloadable files do not appear on your desktop, please click on "(My) Computer" and under "Devices with Removable Storage" your downloadable files should be found. On my memory card, the videos and pictures were stored in the "Data" folder. If you cannot find the files there, please try moving the memory card a little farther in or out of the reader and repeat the process. The input design of the unit isn't exactly precision engineered, but for $4 and considering how well it finally worked, I cannot complain. My memory card was not damaged in any way after having used it with the reader. The card is now back in my phone and is working perfectly. Good luck!Update 5/17/13 I used the reader again today and it worked right away the first time. My videos and pictures downloaded very quickly. My memory card still works fine in my phone with no problems.Update 9/25/13 The unit no longer works.

I had a MicroSD card that I needed to create an image of, then duplicate to a blank MicroSD card. In other words a clone. On my Windows 10 Machine, I use Win32 Disk Imager to create a backup for my rasberry pie SD card. Insert and let the program "read" the card, then it creates an image. Eject original card and insert blank card and "write" to it. When finished, click on the verify button which compares image to new card. Works flawlessly with this card reader. Other will not work with this program. Windows sees the card but the program fails to recognize the drive letter. Buying 3 more of these as they work for my purposes.

The actual Red & Black SANDISK item is excellent. It feels heavier and more solid than the Monster version that at least one seller is shipping when you order this. Buy from BLUE PROTON - it says who the seller is at the top just under the price.I bought this from Digital Media Source for $3.99 with free shipping and it came directly from them. What I received was a Grey & Black item labelled Monster. I contacted Amazon to complain of receiving the wrong item & they contacted the seller on my behalf stating I wanted a refund, and that if they wanted their item returned to send me a prepaid label. Digital Media Source did not reply, so Amazon refunded my money. I complained because of the other 1 star reviews that said the grey and black one had problems.About a week later when what I originally wanted showed as back in stock and I was buying something else, I bought this same item from Blue Proton (fulfilled by Amazon) as an Add On Item (with free shipping). From BLUE PROTON I received the correct, high quality, SANDISK MobileMate. (And, interestingly, it's not an Add On Item today.)5 stars for SANDISK, BLUE PROTON, and AMAZON. -2 STARS for Digital Media Source - false advertising & failure to answer customer complaints (they get 3 stars for fast shipping - so better than the full -5 they deserve).I don't know about other sellers - if you have the time to risk it, you could use a different one, and if you get the wrong item, tell Amazon - they will make it right.

Just got it, not sure of long term durability or function. Drawback: if you’re clumsy or have limited mobility with your hands, this thing is TINY! Very hard to pick up or insert into a USB port.... GOOD: SD card fits in tightly, doesn’t come out easily making this a good choice to hold/store a Micro SD card! Got this because the standard adapter for my 1TB micro SD card was lose, and protruded from my laptop so it was easy to lose. I added a very LIGHTWEIGHT keychain to keep track of it in my laptop bag, and to help me pick it up since it’s so SMALL.

I carry lots of "stuff" on my smartphone, which I increasingly use as a replacement for a laptop. (The Sprint HTC Evo 4G with a wireless keyboard is a fantastic combination. Smartphones and convergence are actually happening.)Usually I upload files that I might need to the "cloud" or email them to myself.But for music, movies and other voluminous masses of data, I use a USB cable - which I often don't have with me in the field.Enter this handy little gizmo, the SanDisk SDDR-121-A11M MobileMate Micro Memory Card Reader. Take my microSDHC card out of the smartphone, pop it into this gadget and plug it into a USB connector. That's all there is to it. Works like a charm without hassles.It is a lot more convenient than the SD card sized adapters because it has a lanyard and will fit on a key ring.Build quality is adequate and I do anticipate having to replace it somewhere down the line. A small price to pay for the convience.If you have a smartphone, MP3 player or other gadget using a microSDHC card that you want to transfer data to or from, this is literally the perfect solution.Jerry
