I ordered one. It's nicely made and sturdy. The phone fits nicely on the plate that fits on the adapter. The only problem is it wouldn't fit on my Hawke Sidewinder so I sent it back.
Bit late to this party, But i have a g-line adaptor,iits a great piece of kit and mounts very solidy , you can get different inserts to fit different bell housings Im just waiting for a reply for a new mounting plate to fit my samsung s7 ,and then will drop some pics on Rgds steve
