I bought into this quite a while back and it does not stay tight. I went thru different mounts at great expense, having the spring 'updated', it sits in the safe.
By now, perhaps there is a repair for this.
I would like to avoid another purchase, I am timing out. A lighter unit with real engineering that works does sound good though.
Any advice?
