Query: cool flexible keyboard that lights up!!

Cool flexible water resistant keyboard that lights up. I like how I can roll it up. For some reason there are two extra unmarked keys that don't do anything to the right of the space key, which is smaller as a result. The keys are also a bit far apart and you have to hit them pretty hard and dead on in order for them to register. Given the key spacing the the stroke distance, this is not a speed typing keyboard. It is a good portable keyboard for your laptop that can be used in the dark and basically jammed into your bag. So for limited purposes, where you want a full size keyboard that does not take up too much space, this is a good product. Also nice that you can just rinse it off (haven't tried this yet).
