I just purchased this and it's a very smartly designed and durable keyboard. Once unfolded, the keypad itself slides together to lock the unit down flat. It feels and types just like my laptop. It's stable, and the rubber feet on the bottom keep it from sliding. It also has it's own form fitting zip up carry case.My only complaint is that the keyboard arrived without the Device Stand included. Instead of repackaging everything and sending it back I've opted to contact Think Outside (which you can only do by email on their site to my knowledge) to get it sent to me directly. I'll post again if I don't hear from them soon. :)
