I think they've done a decent job of showing how well it holds devices, BUT, I think they'll have a difficult time really getting us to believe how secure it is until we can actually feel it on a bike. If they can get these into shops and have people actually touch it, I suspect it would have a huge impact on the naysayers (like yourself).
