Arrived quickly and is a small, well made item - first impressions very favourable.
Took M2 card out of my W995 (note this won't take the micro SD cards common in a lot of phones - the slot's too big for starters !), and plugged into laptop USB. Immediately recognised as a separate drive (Windows 7 HP 64 bit) and could start to transfer files straight away. Love the swing out design that protects the USB connector when not in use, and also has a small hole at the top for attaching a lanyard.
If you have an M2 memory card and don't have a USB lead for your phone, or you do and are just having trouble getting your PC to recognise it, I can heartily recommend this device - and at the price it's an absolute steal !
