I have this on a .22 pistol with 2000 rounds on the scope now. Zero issues. For the price, this is an outstanding deal. It is very bright, and it will hold up for target shooting, but I would not trust it on a 5.56 rifle or any type of serious action, it just does not seem that tough. The mount screw is tiny and seems to want to strip easy, although I have not had a problem yet. Mount it on something light and leave it, should work out great. Don't think this is a replacement for an aimpoint t1/h1.
Pros: Cheap, works
Cons: Definitly not a replacement duty gear
