This is a surprisingly adequate single pin sight. I wasn't expecting much when I ordered but am quite happy with the product received. The slide action is nice and smooth. Windage adjustment has a little slop (each click is not precisely the same) but nothing big enough to cause a problem for hunting. It's all tool-less adjustment btw, aside from the initial elevation adjustment you do for 20 yards/20m with the sight at the maximum height position. The description doesn't mention it, but the sight comes with a battery powered light that screws in to make the ring and center pin brighter if desired; it has three brightness settings.

-1 star as it does not come with any pre-made adhesive strips for distance. You have to sight it for each distance manually and pencil in on the blank strip it comes with.
