This soft and flexible keyboard is pleasant to use. It's light is very flexible. It fits easily into a bag without taking up too much space. Obviously it is waterproof and it can be washed and spent underwater. Wireless USB detection problem, no special configuration. The finish is had all the same as with a conventional keyboard, you must press more firmly on the keys. Small problem with the space bar, which remains active when the keyboard was rolled a while she remains depressed, which makes using the keyboard not the time it returns to normal shape. Good product anyway.
