I'm glad to see that some people have had good luck with Simmons! "Luck'" being the key word here!
I had a Simmons Aetech that failed on opening day of deer season. Fortunately for me, I did not have a shot that morning, and I caught the failure before shooting at live game!
It took me about 4 months to even get through to Simmons, and by the time I did get through, I didn't even want a replacement, all I wanted was to "vent!"
Long story, short, Simmons DID finally send me a NEW scope. I didn't want anything to do with it, and thought about selling it!
I could not in good conscience "pawn junk" off on someone else, and ended up throwing it in the garbage!
