Query: I was surprised.

I set this in a very heavy door and deadbolted it shut, since I didn't want the band to come flying back at me. Didn't matter, as I'd only just reached a distance where the resistance would be noticeable (about 8-10 feet) when the band slipped through the ring on the handle from the tension and flew back at me. It's not even usable now, and I'll be seeing about getting something different in a few minutes. I would have thought it'd be built to have the band break before it could come apart like that.
