I bought one, just because. I mean it was sooooo cheap. I put the 2x7 on a Ruger Mk II about 3-4 four years ago....and it has been there every since. I would not trust it on anything larger the a .22 but for a rabbit shootin' or IHMSA prone where I mostly shoot in full light (I don't think it gathers much light)it works just great. I don't use the power adjustment much and I don't know how it would work out for hundreds of movements but I have to admit that I have gotten more use then I ever expected out of it.
