If you don't know the story, I hunted with my Mueller APV in the rain. The scope was foggy the next day. I adjusted the eye relief that morning and most likely, it was my fault. That never mattered to them, as they replaced the scope and sent it quickly back. I sent the scope back Thursday of last week and received it back today( Wednesday). You can't ask for a quicker turn around. I'm in South Carolina and the scope had to travel to Michigan and back during the holiday rush. That is absolutely unheard of. They even sent me a free sun shade for the trouble. I will definitely be a customer for life. Thanks, Mueller and the board members for recommending them. They truly are a top notch company.
