Other than that....they're wonderful. I've been hunting with a Carter Just-B-Cuz for 10+ yrs. It's never fallen or been knocked off my string (from stand). That's the first thing people who don't hunt with them will cite. Could it happen? Sure. I've probably hunted with mine an average of 100 hunts/season for many years.
I switched to a Scott Pursuit this year and have been loving it. It comes with a wrist strap so you can keep it like a index release if you want but besides better shooting I like being able to hang the release on the bow while in the tree.
I've shot Carter releases for years, with the Ember1 being what I have been shooting for the last 10 or so. It has the open hook, so you can't leave it hanging on the string as DBCooper described. But its my all time favorite and I'm comfortable with it and that's the main thing. Carter releases, or hand held releases in general are expensive, but in my opinion you will never sqeeze the very best out of your shooting ability without one. At least that was how it worked for me. I think hand held releases magnify the shooters bad habits, so it forces you to abandon them.
I guess i've been lucky because i've been using the same Fletchunter Concho for about 30yrs and it's still going. I liked it so much that I bought an extra one years ago cheap on ebay in case this one broke or stopped functioning but so far i haven't had to use. I've used it so much that the rubber sleeve is in a half moon shape where it has formed to my hand. It has definately been a good one and has functioned flawlessly since the day i bought it. Got my money's worth for sure.
Best deal on the market. Quality and price is what I’m referring to.

Once I picked up a hinge I ditched all other releases to learn to shoot it.
10+ years later I love it. I have shot many brands, shapes and styles
Since the Scott “backspin” came out I’ve kept that one.
Seems to fit my hand and face well.
I shoot a Stan because it fits me best. Thumb releases and hinges are like pistols in that they need to fit you to shoot it well. I shoot my thumb trigger the same way I shoot my hinge but I dont hunt with the hinge.
