I got one of these and it seems to be pretty good for the price. It's no Leupold for clarity, but it's usable right up to 24x. I just started using it, so I don't know whether it will hold a zero, but I'll be trying it some more with my .22, then putting it on a .270. I'll post my findings. Eye relief is short at higher magnifications. I like the mil-dot. The reticle is about the right size for prairie dogs out to 300 yards.
Shots hit the same point of aim when magnification is changed. I have not tried any of the repeatability tests, because I don't need them, but four clicks does seem to translate to 1" at 100 yards.
So far, so good. If it holds a zero, it'll be alright for my occastional prairie dog trips.
This is an $80 scope.
