The Progear Voyager requires a coin in order to loosen the connection between both parts. Even after it's loose, it still requires a bit more work to separate both sections. It's certainly a risk that the two could separate upon impact, but I think it would have to be a pretty high fall in order for that to happen. I actually had the regular Progear case for my 6+ and slightly prefer it over the more heavy duty Voyager model. Unlike the Voyager, the normal Progear is just one piece and has this rubber like material all along the inside
