Hey, all. Has anyone had actual experience with the AR-332 sight from burris?

http://www.burrisoptics.com/ar332.html

On the surface it looks good. price is right, features are nice, and seems usable.

However, i saw some nasty early reviews from right after its initial release. were these just teething problems, or has it persisted to be a problem product?

Before anyone makes the smart ass comment, if I could AFFORD an ACOG, I wouldn't be asking after the burris.

So, anyone have one they are happy with and still using?
