Familiarity: I've used it several times
Bottom line: I'm a bicycle commuter, and I'm sick of carrying around a big clunky harness every where I go. This is harness is awesome.
My friend lets me borrow his harness when I forget mine at the gym. I'm pretty forgetful, so I've used it a bunch of times. Finally, I'm getting my own. For me, the harness is super comfortable, and packs down into nothingness. I probably wouldn't use this to trad (because of the lack of gear loops), but this is the harness for indoor or sport climbing.
