I've been a bow hunter for years but had complete arm replacement and can no longer pull my bows and was given a new PSE vector for Christmas which at first I loved I was preparing to go deer hunting next week with my son so I started shooting my bow and the wheel broke and notched the string. here I'm wanting to go up to my sons this weekend and PSE don't have the parts in stock. I only fired this bow 50 to seventy time. only 5 times the day this happened, has others this with this bow
