1.2FT Extension Cable + USB3.0 + USB C CARD READER

Worked with all the types of memory cards I had.

Connect to labtop easy.. transferred photos easy! No issues

I purchased this so that I could move photos from my cards onto my cell phone. This one has a reader for xD cards which I want it because I have an old Fuji camera that uses that type of card. So far I have used it with an SD card and microSD haven't tried xD yet. Works fast but instructions are vague so be careful to put the card in the correct slot. If you need a lightning connector for an Apple, such as iPhone, product you need to order the size Large as the Medium (what I got) does not have that connector.

Good

The plastic is cheap and the cord is super short and stiff (cheap materials). It does work exactly as advertised tho.

*** Rocketek's card reader INSTANTLY CORRUPTED one of my Olympus xD-Picture cards. If that camera had any photos on it, they are now unrecoverable. AUTOMATIC NEGATIVE REVIEW. ONE STAR. THE END. Olympus camera owners are strongly cautioned to continue downloading photos over the USB cable that came with the camera; do NOT use the Rocketek device. I put Rocketek's card reader through a lengthy series of tests. I was able to prove that the Rocketek card reader quickly and reliably corrupts a working xD-Picture Card. In each test, I reformatted the card in the same Olympus camera I have always used the card with, and I edited a small text file on the xD-Picture Card using the `vi` editor in a new Mac mini computer. Half of the tests tethered the camera to the computer using the camera's USB 2 cable, and half involved plugging the xD-Picture Card directly into the Rocketek card reader (which of course was already powered up on a USB port). In all tests involving the USB 2 cable, the edit works, and Disk First Aid finds no problems afterward; however in all tests involving the Rocketek card reader, this simple editing procedure CORRUPTS the xD-Picture Card beyond retrieval, so that all files on the card are lost and unrecoverable, and reformatting the xD-Picture Card is the only option left. I also had great difficulty formatting a 128 GB SD card using this device. I had to restart 4 times, wasting about 2 hours each time. Symptoms suggest that Apple's device driver simply fails and hangs due to an I/O error when using the Rocketek card reader. ***** Based on this, my business will not be trusting *any* of Rocketek's devices with *any* of our data, on *any* kind of flash memory card. Shoppers who want a trouble-free card reader should try the one made by Uni, at Amazon Item Nº B08P1T8R46. It's a faithful work horse and handles my biggest encrypted backups without fail. Has write-lock sensing, meaning it won't alter your archival drives. Sadly, it is not a hub and uses up one USB port. Other Problems: • Adaptor plug (Rocketek's adaptor that converts USB cable to USB-C) is too fat to fit in a Mac mini -- it bumps up against the HDMI connector. So I plugged it into the *other* USB-C port; this left the middle USB-C port inaccessible. (Rocketek's adaptor is 17.8 mm wide; Apple's USB-C ports are centered only 15 mm apart.) • Worse, the Rocketek unit does not even function when plugged (through the adaptor) into the USB-C port. The power LEDs (both red and blue) briefly blink on, then go dark; when I inserted an SD card, the card did not mount. I will not accept a refund nor a replacement. Last time I accepted a refund, Amazon removed the words "Verified Purchase" from my review, which sank my review to the foot of the page. I prefer to warn good customers about bad products. About the author: Software developer and business owner. About the video: The Rocketek scrambled my data, so I scrambled the Rocketek. Caution: Fragments will fly! Always wear safety glasses when disposing of defective hardware.

The device works. I have not tested the full data read write abilities \ 5Gb but I can say that all of my SD, Micro SD, and Flash card ports work. Data transfer speeds met each card's transfer speed and write speeds to and from for my desktop. I was able to migrate data on multiple cards to my pc at the same time along with moving data from one card to another at the same time.

it works well with all the flash cards. it eliminates the need for all those adapters in the computer.
