I have several sets on my rifles. They look good, and return to zero.
They did have some quality control issues though. Ring halves seldom matched up and all had to be reamed with a 1" Clymer scope ring reamer to prevent denting the scope body. They also sent out defective base mounting screws at one time, they snapped off regularly. (Lest anyone think I was meathanded, to their credit they admitted the problem).
They were a pain in the ass to get right but once they were right they were good.
Customer service was good but I like to think that the best customer service is the one that I don't need, they get it right the first time.
I still have a couple of sets that I'll probably use just because I have them but if I were buying new I'd spend the extra money for the Talley's and be done with it
