i got my draw-loc last week and did not have any problems installing it on my bow. i was shooting targets arrows in less than 1 and 1/2 hours. tighter groups came very easy. i shot at least 20 arrows(the first arrows i have shot since i hurt my shoulder in sept. 2007) i was not tired,shaky or blinky. my follow thur is much better.i'm 53 and all my hunting buddies are at least my age or older. most are trying crossbows, untill i started telling them about draw-loc and was looking forward to seeing it in action. i started hunting the next week on my days off. i seen a couple small bucks, easy 20 yard shots but i let'em go. weds.afternoon i got in a stand about 3:45 , just as i got all settled in just watching the leaves fall, i dropped my bow out of the blankey blank tree,about 15 feet right on a log, ugly site. cables everywhere , peep sight is problly has not landed yet. but the draw-loc system held up perfect.  our rifle season starts sat, so i'll put this train wreck on the shelf till late next summer and look forward to next fall. great product. my old  ben pearson with the draw-loc is still lighter than a $800 crossbow and i'm still bow huntin'. thanks a ton, get ya a big'en good luck and thanks again
