The biggest problem with this reflex is that it doesn't shut off completely, even with the cover. As a result, it will kill a battery in what seems like just a few weeks. When I contacted NCSTAR, they said it was normal and that battery shelf life is only a few months. The only way to prevent this is to remove the battery every time, which is not trivial since you have to remove the base. Otherwise, it's been great for the price I paid, but I think I will just pony up for a Burris Fastfire. Better value, in my opinion.
Pros: Compact, cheap.
Cons: Eats batteries.
