Things I liked:The Idea
Things I would have changed:They should go back to the drawing board. The set screws strip. It wont stay adjusted.
What others should know:This just didnt work for me. The adjusting screws for windage are just WAY too light weight.
Things I liked:I like that it's the only adjustable medium mount out there apart from the RWS C-Mounts
Things I would have changed:The screw quality is bad. On the base screws the hex holes are not even centered on the screw heads or of a consistent size. The one I got had the windage adjuster screws too small for the tapped holes... or the holes were too big? The net result was a totally unusable mount, I sent it back for a refund (refund pending) and got the Beeman 5032 instead.
What others should know:Although the top half of these rings off less chance of squashing your scope tube due to over tightening, They will scratch the tube when putting them on or taking them off if you are not very careful. They have a C shape that needs to be opened slightly when installing / removing to prevent scratching.
