Excellent just what I wanted for sub zero nights with cold fingers!

I fully agree with the previous review. The last thing you want is the scope falling off because you've not tightened the hand bolt(s) enough - well this gives you that piece of mind. As an example, if I fully tighten the bolt by hand, I can get another 1/4 turn with this tool so total piece of mind. I'm not aware of any other manufacturer doing something similar so well done ADM. 5 stars!

I pondered this purchase for a while because of it's price and also it's potential value in my armoury, anyway i went for it and to be honest was more than pleasantly surprised to find out just how useful it turned out to be, way more easy access to the saddle knobs and a sense that their done up nice and tight but with a lot less effort, so at the end of the day i'm well pleased
