PABowhunter. not to argue with you but I have installed a MZE on two of my bows and couldn' t have had it any easier. If you just follow the instructions on the video it should be a breeze. My first time setting one up was on a Diamond Recon. I followed the video, then eyeballed the horizontal setup in and my first 3 shots were perfect bulletholes. Done and ready to hunt. My second time was my present set up on my Q2. My first shot, slight right tear, 2nd shot a little better and the 3rd shot perfect. Done and ready to hunt. I am sure that not everyone had it that easy but it was a breeze for me. I know another guy who had his set up pretty quickly also. I thought that the video, over reading, made it a whole lot easier. Just my experience. Like I said, not trying to argue with ya Pa, just relaying my experience. My buddy and I who set it up with me were shocked at how easy it was. To be honest I was a little intimidated at first. It looked like it would be a bear. But I was pleasantly surprised.
