Sorry you've had such a time hooking it up. But I have to tell you, it's the greatest once you get it working. I banged mine around in snow, ice, rain, brush and my car for a year now. It just keeps ticking. Len in MD put mine on for me and had it shooting bullet holes in about 15 min. It's been perfect ever since. There have been a couple minor adjustments necessary with string stretch/replacement adjustments etc.
