Things I liked:The customer service at Pyramid air is outstanding Things I would have changed: I feel like I am reviewing a different product than everyone else. The first one I recieved seemed to be defective, parralex float at 50 yards was at least 12 inches. I E mailed customer service and they shipped a replacement out to me in 2 days. The problem being that the new one is just as bad as the first. Not even usable for close range. What others should know: Don't go cheap, you get what you pay for.
