Defective cable, the USB adapter does not make good contact with the computer port. It reads the cards but the cable constantly needs attention.

I got it to transfer files from an M2 memory card of an old Sony Ericsson phone. The laptop recognized it immediately and the transfer was done in a flash without any problems. The construction of the card reader as well as the length of the cable that comes with it seems quite high quality. I recommend it!

You need to connect it to the back USB ports of the computer that go directly to the motherboard to have a connection without any problems. Nevertheless, it's a very good reader; I got it for cards from a Sony Cybershot digicam

It was defective from the first day, the cable and card reader kept disconnecting constantly. In the end, I managed to make it work only once and now it's done; I can't even get into the account to send it back so they can replace it for me.

This specific card reader is very good. So far, I have used it with a memory stick duo and an SD card for file transfer, etc. It is easy to use, cheap, and the quality is quite good, especially for its price. I have had it for about 2 years and it has not presented any issues so far

The micro SD couldn't fit, so I removed some plastic in order to make it fit, but in the end, it still didn't read them at all.

Very good and works perfectly with Windows XP. A good choice for anyone who has cards and cannot read them otherwise.

It does everything it says! Very convenient and economical! It has saved me so far, especially considering its low price! I mainly use it for camera memory cards. Works great!
