FWIW, I'm at 10 Holosuns now. 6 of their pistol sights, and 4 of the rifle mounted Micro clones. None of them are babied, and all hold zero and work as required. The only one I had trouble with was the first one I bought about 8 years ago, when the brightness buttons stopped working consistently. It was replaced by Holosun with an upgraded model, inside of a couple weeks, that has seen about 10k rounds since.

From what I've seen, these things don't seem to fail at a higher rate than Trijicon, Eotech, or Aimpoint. Though I'm a firm believer in BUIS on all the things, I trust and like the Holosuns I have, and recommend them to everyone.
