Pretty good overall - Bushnell 1x28mm Trophy Red Dot Sight 730134

Pretty good overall, with good battery life, bright enough display to see in bright sunlight (with the sunshade attached), and multiple reticles. The parallax is bad enough that it can shift my POI by 3+ inches at 100 yards though - if I'm shooting for groups I have to make sure and not come up off the rifle between shots or group movement can be severed. Also the final notch on both reticle settings doesn't like to lock in every time, so you kind of have to rock the knob back and forth until it settles into place. For what I paid though it seems like a good enough deal, mounted it on top of my converted Saiga and it does the trick nicely for if I'm too lazy to use the iron sights.
Pros: Cheap, good battery life, light.
Cons: Parallax, reticle float
