I needed 30 min. to get the light on... the CR2032 was brand new but I could just see very, very little light. A friend told me to use some paper made of aluminum. That helped and fixed the problem with electrical contact. That was my only problem. This scope is the best I ever had. I would buy it again.
Pros: cristal clear optics, perfect illumintion, nice tubs
Cons: to fix the batterie
