I have found many various occaisional uses for this device which also works fine just like an ATC. Why not have additional functionality with hardly any additional weight or price?
I like the way it rappels and belays, and I like it much better than a Gi-gi for belaying two seconds. Smaller diameter ropes work great and 10.5 isn’t a problem if it is a “slippery” limp rope. You won’t be able to bring up a second using a 10.5 Stratos cable or other stiff ropes though. I even belayed myself up a 5.10 slab route on TR. It’s cheap too, many more tricks possible than with an ATC. From: Kai Larson I’ve used my Reverso quite a bit. It pretty much works as advertised, functioning as both an ATC device for belaying the leader and rappelling and a GiGi device for belaying one or two seconds. My only gripe is that it doesn’t provide enough friction in rappell/leader belay mode when using 8mm ropes. When using new 8.1 mm ropes, I found that I needed to use two carabiners to provide enough friction for long free-hanging rappells, even when wearing gloves. This isn’t too big an issue, because you need to use two carabiners to use the device in autolock mode, so you probably are
