I have a 2-7 the first year they came out and it still works great. The only problem I have ever seen with it was a friends fault. He had to get one because I had one. I told him to set it on four and don't mess around with it. Jumped a good buck and it went straight up to him on a dead run. of course he had been fooling around with it and now it was set on 7. Nothing but hair in the scope for three missed shots. He bought the drinks that night.
