I purchased one of these for £20 from argos around 9 months ago now. I bought it so I could listen to music on my mobile phone whilst on the train - its served me well and still retains a place in my phone.

It can store approximately 35 albums on it, which provides more than enough variety for my needs. I also use it as my main storage for pictures when I take them on my phone. It has always been reliable - and although its small, I've never had the problem of misplacing it as its always inside my phone. Keeping tabs on my phone is another matter completely!

At the time I really couldnt afford a larger capacity disk, and looking back I'm glad I didn't waste money on more. Within the package I purchased from argos I also recieved a converter, which you can slot the m2 disk in and it fits in larger slots of other devices (card readers, digital cameras etc.) which was an added bonus. I have problems with the USB on my PC, so its faster to just chuck the memory card into my girlfriends laptops card reader (with whom now I live with) and transfer the photos off it that way!
