I had a bad experience with Burris CS myself. Sent a 2-7 Compact in for flecks of stuff floating around inside. It took a couple MONTHS to get it back- but what was worse is that they did the cardinal sin of CS, which is saying several times "it's shipped!" when in fact it wasn't, and wasn't even going to be for weeks!
Oh, and the flecks came right back.
I had a similar experience with a 1.5X6 Signature Series scope. The first time it fogged up on a nasty season opener and cost me a day worth of hunting to return home for a different rifle. When I got it back from Burris I remounted it and resighted it during the following summer and when I pulled it out in the fall there were several flakes of what appeared to be paint on the inner lens. Back again but who knows for how long.
I do have another version of this same scope on another rifle and have never had a problem with that one and it is a great scope on an elk gun. Great field of view and very bright under low light conditions.
