Not sure how stable you need a dock to be, but once I put my iPad on the dock, it's not going anywhere until I take it off of the dock. It utilizes the Lightning cable and it stays put. Now if you plan on hitting it or throwing something at it, then maybe it will fall off. # Stability has never been a concern...the interchangeable rubber inserts (to go from naked to having cases on devices) provide the stability. It's also completely interchangeable with devices. The one in my living room charges all iPhones/iPad Mini's and iPad's in my home.
