Perhaps, but I think the reviews were what they were. I've seen glowing comments from TFB about dime store optics, including PA, so I'm not too inclined to think it was a determined hit piece.
There were four Holosun optics in the two linked reviews. All four failed. Two stopped working entirely. The auto-on failed on one, and a lens fell out of another. I think it's more a reflection of Chinese quality control. Some work absolutely perfect and others may have a variety of issues.
When I bought my Primary Arms Compact 4x about four years ago there was a BIG stink about the reticles being canted. Pursuant to that, Marshall made sure the reticles were checked before being shipped. Where did the others end up? Probably e-bay or..... That's why I have repeatedly recommended doing business with Primary Arms when buying this level of optic. They have a solid reputation for making things right. So you get a great one out of the box or maybe happen to get one that isn't and Marshall replaces it. Either way, you'll end up with a solid working optic for recreational use.
