SanDisk SDDR-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 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

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.

I bought this more out of necessity, as loading media onto micro sd cards for use on my phone was understandably slower when done over wifi. This adapter is priced super low, and I've had good experiences with sandisk products. It's read several microsd cards without issue, and works just fine on linux as well. If I have a complaint, it's that the data transfer speeds are pretty low, even with high quality micro SD cards. If you're looking for something to use as an ultraportable thumb drive for data transfer, then I recommend checking out the sandisk cruzer fit, which is a spectacular drive.

Great for writing too or reading from microSD cards with a computer. TINY...the size of my pinkey finger from the end to the first knuckle. Small enough that I think I could swallow it if I wanted too. After I write to a card, it and the card are warm to the touch, not hot. It has supported fast file transfers with several UH-1 class Sandisk ULTRA microSD cards I use, at speeds over 20 MB per second, and has worked well for some slower cards too. Neat LITTLE gizmo. Just what I was looking for, as microSD is the only flash memory card format that I use. If you use multiple types of cards, the full size Sandisk multi-card reader may better suit your needs. Another quality Sandisk product! Be aware that this product has been copied and that knock-offs of unknown quality are on the market. I purchased mine from MEMORY EXPERT for $3.50 with free shipping, and recieved a genuine sandisk unit with a serial number, in its original packaging.

SanDisk microSDHC 8GB と合わせて購入 小さいし使いやすい

Fait la job

超コンパクト。でもその分なくしそう･･･。 問題なく使用できてます。

Fonctionne parfaitement bien

元々は我が家のPCがSDHCに対応していないので、アクセスするために購入した。 届いてびっくりの小ささ。もちろん使う上で問題はないが、最大8GBのUSBメモリと考えると、今、持ち歩いているのが巨大に見える大きさ。マイクロSDを入れても出っ張らないし、デザインも悪くない。どう使おうか悩むところが問題点。 SanDiskさん、お願いだから色違いを出して（お願いついでに言うなら、「なぜ、マイクロSDは黒ばっかりなの。色違いをお願い」。手持ちのSDカードもメモステも、中身はマイクロSDなのに、区別がつかない）
