Review on Bone Bike Tie Connect: Universal Mount for Garmin GPS Cycling Computer & Phone - Handlebar & Stem Compatibility by Lee Wilson

Innovative design that allows you to attach your phone to a Garmin style quarter turn mount. Utilizes a secure, soft-backed bungee design. The phone has a little play when going over bumps. It probably absorbs shock well, but it's a bit more difficult to use the phone in the holder. You can use whatever case you need rather than needing a custom case like the Quad Lock and still get the convenience of a quarter turn to attach and detach for a quarter of the cost. Excellent design, there are no analogues on the market.
