Let me start by saying if you don't have enough common sense to purchase a sight fit for your gun than you shouldn't be shooting. What I mean is hey why would you think you can spend like $35 on a sight thats going to be good for a high caliber rifle?!?! I put this sight on my GSG 522 which works perfect. I wouldn't be dumb enough to expect it to be great quality on my AR or SKS for $35! If you are mounting this on an air soft gun, or rimfire I would highly recommend this! if you want to put it on a centerfire, then maybe read up on your firearms and realize you should spend at least $150 on a sight if you want resonable quality.
Pros: Price and quality
Cons: Not idiot proof
