I've been using one for a little over a year, and it works great. Someone even spilled a drink on it, but I don't recommend testing that. I don't think there is a way to get to the insides of it.

Overall, great range, soft typing slim keyboard.

NOTE: this is NOT the diNovo Edge, this is the cheaper wireless keyboard without the charging base and everything. I've seen it at this price for a while and it is not worth it. If it was the edge? definitely!
