IMHO, these are of more than adequate quality. It's like getting the Caprice Police Special instead of the Impala (early 90's lingo). Same stuff without the cache of the name. They haven't been around long enough to ascertain their longterm durability, but, on the other hand, you're only spending a Franklin. For the cost of the Aimpoint you could outfit your entire battery of blasters. Now, don't misunderstand me, I have two Aimpoints and am not disappointed in the least with any aspect of them, cost notwithstanding. In a "blind Taste Test, I don't think you'd notice the difference. Nuff said. Like the guy in the old Pepto Bismol ad said, "Try it, you'll LIKE it".
