Had three.

03 Black Knight II shot it for three years trouble free.
06 Allegiance, had a bottom limb crack the second year I had the bow. Had replacment limbs from the factory in less than a week. They didn't have any in my camo pattern in stock. Got another set three weeks later in the correct pattern when they became available. They said just keep the other set. Great CS through this ordeal.
08 82nd, have had no problems with this one.

Have liked them all and have had great CS from Bowtech. Bowtech shooter and the rest of the affiliated guys on this site are great. All emails and PM's I've sent have always been answered in less than 24 hrs. Great company and great products.
