I was a little bit sceptical about this product. How can something that small be any good??
The truth is:
It's tiny, it's well made and it's worth buying.
MicroSD card sits in it securely and you can attach it to your keys to make sure you will always have some electronic storage with you if you need it.
Reading and writing speeds are OK, and I had no problems with this device being discovered on any Mac or PC with Windows XP/7 or Linux.
That's it. There is nothing more to it. It reads microSD cards really well and if you are looking for a really decent card reader, you've just found one!
