When it works, it works well, but the bungee broke about 12-15 shots after I first tried it. I reattached the shortened bungee, and it broke again after about 20 shots. Then I put the new replacement bungee/pocket on, and it broke after only the second time I used it. I'm not pulling it back too far, either. The rubber used in these bungees is junk.
