For a scope that's only about $70, this thing is really impressive. I was skeptical that it would even hold zero, but it seems to do just fine. The glass isn't high end by any stretch but it's clear enough. There is some distortion around the edges, but again, $70 so you can't be too picky. What really impressed me though is how forgiving the eye relief is. I expected this scope to have a REALLY tight eye box, but it's actually comparable to my $700 vortex.At the end of the day, it's still a very budget scope, but I'd take this over a $100 - $150 basic 3×9 hunting scope any day
