My Reverso accompanies me on alpine routes and enduro link-ups where weight is a consideration. I have used it multiple times on free hanging raps with lines down to 7mm (as in double stranded 7mm raps) without any issues. It's not rated down to this size so you'll need to use your best judgement. They wear out faster than something like an ATC Guide (to be expected) so I opt for the ATC when I'm cragging.

"My favorite belay device; super lightweight, does what it's supposed to"
01/22/13
I got one of these to replace a Reverso 3 that had been stolen. It works well with all diameters of rope that I have had in it, and it feeds smoothly. I think it is easier to control slippage for a dynamic belay than with the Black Diamond model. Autoblock setup is a must-have for belaying from above. It's crazy light, to the point that I would actually prefer the slightly heavier Reverso 3 for the more substantial feel. I haven't had any durability problems, that's just my preference. Also, just FYI, out of the pictures here only the orange is a Reverso 4, the others are 3s. You can tell where the sides of the 4 have been machined in, where they're smooth on the others.
I had a Reverso 3 that was stolen, so I got one of these guys about six months ago. Like the 3, the 4 give a smooth belay with all the ropes I have had in it, and autoblock setups like this are the best way to belay a second from above. The 4 is definitely made to be light, to the point where I would actually prefer the marginally heavier 3 for the sturdier feel. That being said, I haven't had any durability problems with the 4, and I have been very happy with it. Also, just FYI, out of the pictures on here, only the orange is a 4. You can see where the sides have been machined in, where the others are smooth.
I had the Reverso 3 for just under a year before it wore down to unacceptable sharp edges in multiple places. We've got a regular ATC and an ATC-XP that are much older and not nearly as worn, so we just replaced this with an ATC-guide...we'll see how that one lasts! Also, I found it was not good with fat gym ropes--had trouble feeding out slack fast enough when lead belaying--but didn't have trouble with it on our 9.8mm rope when climbing outside. Other than these issues, we didn't have any trouble using this belay device.
I read supertopo reviews who put it way ahead of ATC but it seems to be desgned for half ropes only. paying out slack on my seasoned 9.9mm was just bad..
