I agree. Pay the cost for the Aimpoint or Eotec. I've tried several bargin red dots and they all fail sooner or later (mostly sooner) but my chief complaint is none are BRIGHT enough for use in broad daylight. The dots just kind of vanish. Anyway, the cheapest I have in the inventory now is the Bushnell Trophy MP. It looks like a ACOG knock off but is pretty bright, easy to zero and (so far) is working well.
