Although the product is now more expensive than when I bought it just a week ago (paid £17.99) I think it still represents value for money. It has a tough rubbery exterior, with a rubber cap. There is a lug for a lanyard too.
It's quicker than any other USB stick I've used with XP, and with Vista it's simply awesome.
There are of course cheaper and smaller products available, but if you want something tougher that you can still feel in your pocket, or want to take a spot of wear and tear in bags or cases, this is the product for you.
