Bought this drive as I wanted something with a fair amount of storage space on it. When it arrived I was impressed at quite how small it is. It's not much taller than a 50p piece. The outer casing is made of plastic and you have to be a bit careful with it, but as long as your not rough with it and don't sit on it then you shouldn't have a problem.
The only real negative side is that the transfer speed is quite slow. It's slower than any other pen drive I have owned and considering its 32GB in size that goes to assume that your going to be transfering a lot of data onto it which could take a while. 2GB of data took me around 6 minutes to copy onto it. Obviously if your not in a rush then this isn't a massive problem but it can get annoying having to wait.
Overall I am quite pleased with the pen drive. The amount it can store and the price made it impossible to turn down.
