Got the adapter in today.
The good - It's easy to setup , allows quick attachment of the phone and quick attachment to the scope.
The bad - if your phone's back is not flat ( like mine ) the phone wants to roll left / right and pull the top away from. Also the upper stop doesn't quite grab the top of my phone it gets the radius of the corner ( on my Phone Moto X ) and makes repeat centering kind of difficult. It works great with the wife's Samsung Galaxy.
I'm in need of a new phone anyway so I will get something with a flat back. Here's a picture I took of a stray cat in my pasture tonight.
