Simple to adjust IMO. The adjustability is a big reason I own the sight as well. I had one of their older models and wasn't happy with some features. I tried a bunch of different sights and always went back to the Hogg because of the adjustability. Still shooting one.
I really don't think this guy knew what he was talking about. Some of the guys working the floor at the Big Box Stores know their stuff but they would be the exception not the rule. Take what they tell you with a grain of salt. Go in and ask them some archery related questions you know the answers too, you'll find out pretty quickly what they do and don't know.
X2, great sight and it adjusts easily.
