Waste of money I want my money back

I took this and put it to the test. I took it to a bow shoot. Just wanted to see if it was worth the effort. It was off every single time. Not even close. You have to calibrate it on every single target and it still doesnt work properly. There were 5 other guys there with me and had this worked they would have gotten it. Thanks for nothing. Can u say refund.
