RE: what is your opinion and why?
I find that kinda odd: I have been using them for as long asI can remember back...I have never had to send one of mine back for anything.A friend of mine did purchase a Leupold off of e-bay and when he got it, it needed purged (nitro).He sent it to them and they could not reseal the scope.It was according to leupold about 9 years old.They sent him a new scope-same power---FREE. Nuff said there.
