I've used one (4 arrow KK) for several years and I really like it. I take mine off @ the tree and mount it to the tree...really handy. I have the older 6 arrow (with single arrow holder) and I didn't like it as well because occationaly an arrow would get loose and vibrate. I am curious about the Octane quivers but $120 just seems crazy...maybe one day I'll break down and give them a try.
