I have this exact model and am very pleased with mine. I am not the best person to judge glass as my scope experience is limited to a handful of scopes.
However, glass is noticeably better than my razor hd, seems about the same as my NXS, maybe a tad better. (Which some might argue..which is fine, but to my eyes that's how it stacks up)
For the money it's a **** fine scope, the zero stop is a little different to get setup but once it's set, it works perfect.
