Accuracy Unlimited is where I bought my Carbon Express Blade 4 crossbow. My strings snapped after a few shots in both of the cams. To get back to Accuracy Unlimited because they would not refund my money, and they restring it after about a week or so I picked it up shot one time and it broke again in the right cam. Accuracy Unlimited in Hayden Indiana again is trying to fix it but will not refund my money. I guess we'll see if they actually fix it this time.
