i just tested this rest yesterday again and i found several things wrong and im done fooling around with it.i was looking for a little better long range performance than my whisker biscut which i used since it came out. i bought the quicktune 360 last year and was liking it for about a week. then the teflon guides and post started wearing out and my groups went out the window. i called the company and they said they re- designed the bottom post and the teflon guides and they sent the new revisions to me. being too close to the hinting season i put the whisker biscut back on. i planned on trying this year. around december they did another re-design using bristles like a whisker biscut. i called and they sent me more parts. well yesterday i messed with it and found there werent enough bristles and probably werent stiff enough to keep the arrow in place all that great. in other words the arrow fell between the cracks so i had to opush it back into place with my finger while at draw. i messed with the adjustments and never got the rest to work. groups were poor and after seversal round the bottom post cracked in half. the bottom post is made of a springy thin plastic. anyway im done being a tester for a product that for me wasted my time. i think they should have done way more testing. so for now im now gonna try those blazer fletching on my whisker biscut to see if my 35 yard hits group better.
