Ran across this one today.
Mount and accessories came today, will get first use sometime this week. It feels very secure, with little chance of accidental release. This is the mount interface, attached to the vibration isolator, attached to the RAM-compatible ball, attached to the RAM socket arm. Not shown is the custom case that attaches to the mount, because it's on the phone that took the picture.I've ordered a Quad Lock system, which consists of a mount (RAM ball compatible), case, the Quad Lock attachment, and a vibration isolator. We'll see.
