Good product

Just what I needed to be able to read all the vaious cards I had for cameras etc.

I was looking for an inexpensive way to copy my photos and videos from my camera onto a new and larger SD card. Since stand-alone card duplicators START at about $130, this inexpensive reader/rider intrigued me.When the unit arrived, I was a little hesitant to use it, since there absolutely NO instructions. And I found the guide drawn onto the unit to be a little vague.I'd read that it was actually possible to put the two cards into the unit and copy one to the other. However, since I was worried that I would do something wrong, I decided to plug the unit into my computer, along with another simple SD card reader.I placed the original card into the reader and the already-formatted new card into the reader/writer. Since I could now "see" both of the cards as individual "drives", it was a simple matter of selecting the entire "root" folder of the old card and dragging into the new one.I placed the new card back into my Nikon and plugged the Nikon into my Mac. In a few minutes, I could "see" all the photos and videos that had been in the old card. I took a few more photos and videos, plugged it back into the Mac and Photos was able to distinguish the new data from the old, so I could import that.Naturally, I would encourage anyone to back up the old card FIRST, just to be safe. And if you're copying data to a new card, make sure that new card has already been formatted for whatever device you're using it BEFORE copying, as formatting afterwards will erase all data.While I would have liked a true manual, this little unit did the job and I recommend it highly.

No issues. Works as promised.

I was trying to download a CF card. I tried everything I could and my Mac would not even recognize the drive when I connected the USB. The light came on showing it was working, but my computer would not acknowledge that it was connected. I even did a search to see if I needed a certain driver installed to use it. I was in quite a bind to get that card downloaded and this was frustrating that it didn't work. I finally searched my box of random cords and found one that fit my old card reader and since it was a lightning cord it took much much longer to transfer but I was able to do what I wanted. But I would still like to know why this charger was not compatible with my Mac.

I tested this with several flash media, and it worked with Compact Flash, SD, MMC, microSD, and xD. I don't have any Memory Stick or Memory Stick Duo. The part the cards fit into is durable, but the cable is stiff, and I can see it splitting or cracking over time. Each storage type shows up as its own drive letter, which is fine by me.It works flawlessly with the USB C connection. The attached USB A adapter is flaky. Sometimes it works, but it will slow down or even drop the connection if you bump it. The cards I tested with claim 160MB/s read and 120MB/s write (Samsung), and 180MB/s read and 130MB/s write (Sandisk). You can see when the USB A adapter is working the performance matches the native USB C. But when it's not making a good connection, it slows down quite a bit. I had one test that I cancelled because it was going to take hours to run due to the bad connection.I'm probably going to try to get a replacement.
