I have the X-Sight II 3-14 and have had it for 2 years with zero problems. If you read the manual first, you should have no problems. Most folks that have issues with this scope are people with light computer skills. Any digital scope is more like a computer than a traditional scope. I have taken many coyotes with mine and I have only good to report on the X-Sight II. I use the factory supplied IR and can get about 200 yds with clear conditions. There is a very good ATN owners forum that can help with most any question you have. I highly recommend using an external power source vs the internal AA's. Weak batteries do cause the scope to do strange things. If you don't want to go the external route, get you some Kentli rechargeable batteries, not just any rechargeables, get Kentli. Most rechargeables start out at 1.2V fully charged and drop off. Kentli store 3.7V and output a steady 1.5V which is the voltage you need. My 16,000 mah power bank will run my scope 18 hrs + and still have more in the tank.
