For such a cheap sight, this little number delivers. If you need a red dot for any reason, and don't want to break the bank, it's hard to go wrong with this. The only problems I've encountered so far, is the lens housing, having some wobble to it, and being a little difficult to zero.
There are 4 allen screws in the base of the sight, two under the lens housing, and two under the laser housing. Take an allen wrench that's one size smaller then the one that comes with the sight, and slowly and evenly tighten both under the housing. If the laser housing wobbles do the same.
