Problems with NcStar DDAC on my S&W 22A-1

[S.B.]

 I bought one of these in camo so it would match my gun. First one wouldn't adjust in elevetion nor would the seceond one they sent me? Both shoot about 10"-11" high at close range(under seven yards). I stripped both the supplied allen wrenchs and the elevation screws on both scopes. These scopes are going for around $70+ locally.
Anyone else have experience with these?

Not with the particular model mentioned, but with some of their products. They seem to be "Hit or Miss". Some work ok, some not at all. The distributor in my area replaces any of his products that are defective for life. It takes a lot of the risk out of buying NcStar.

My main bitch is I'll be six weeks gettting to use what I've already paided for. If it works this time?

Good luck! In dot sights selling for <$100, I've found the smaller ones are less durable. The windage adjustment system really blows.
