 Cred: 2509 | | handles superbly. Works better with the full range of ropes than the ATC guide and does not retain as much heat on long rappells. |
| larger ropes can lock up when lowering and can just be hard to feed with gloved hands. If you climb with a 10mm or bigger, I would recommend the guide. |
| ATC guide for small diameter ropes. |
|
 Cred: 531 | | super smooth, excellent heat dissipation, bright colors, incredibly handy for multi-pitch belaying |
| larger ropes (>10 mm) are a little tougher to push into the device, but still totally do-able (i use a 10.2 with it all the time) |
|
 Cred: 308 | | This has got to be the smoothest belay device I've ever used. Seriously good control. I tend to use larger (10 mm and up) ropes, so I can't speak for the smaller diameters. Can't wait to get out on some multipitch with this baby! |
| I have not found any so far. |

 Cred: 8 | | Review by hoffy on May. 27, 2009 | | the reverso3 functions well with half-ropes (8ish mm diam) in both "guide mode" and standard mode. it also seems to take single ropes with larger diameters (10.5ish) in standard mode. |
| as much as i love the reverso in auto-locking mode with half-ropes, it is an absolute bear to operate it in guide mode with one or two larger (>10mm) single ropes. taking slack is a major chore and can really only be done in 4-6 inch motions with ropes over 10mm diam. with one follwer this is annoying. with two, it can be kind of dangerous. if you never plan on using it this way, this is a non-issue. on the other hand, the bd guide atc accepts these larger diameter ropes in guide mode so it may be a better choice overall. |
| if you are looking for an auto-blocking device to bring up 2 seconds at the same Time on single ropes (>10mm) go with the bd guide atc. |

 Cred: 357 | | Light, works for multipitch. I mostly just use it for sport routes and rappelling down to clean sport routes, but I have tried the multipitch function a couple times just for fun. |
| I have the green, and the anodizing seems to wear off pretty quick. Don't think it's a problem, just hoped it would stay pretty longer. |
|
 Cred: 30 | | Smoothest belay device I have ever used. Ridiculously easy (and, again, smooth) when lowering in auto-lock mode (with the help of a biner nose for leverage). Somehow manages to do this and still have all the friction in the world. I use this in place of my old reverso, ATC and ATC-XP |
| I've heard that it doesn't comfortably take ropes over 10.5mm. It is rated for use with them, it's just a bear to actually get them in there. |
| This is the recommended alternative to everything else. |

 Cred: 22 | | Review by billb on Sep. 06, 2011 | | Feeds smoothly in both lead and auto lock setup |
| when using it in Auto lock for the second the hole that allow you to lower is designed for a spirit caribiner. this means most biners won't fit. |
| ATC Guide but it doesn't feed as well. Just have to wait for reverso 4... |

 Cred: 390 | | Review by Zeric1 on Mar. 28, 2009 | | Lightweight, feeds fairly well, multifunctional. |
| autolock mode works but requires a lot of effort to pull the rope. |
|
 Cred: 22 | | Superb, very light and smooth. Works well in autolock mode. |
| A bit tricky to operate in autoblock mode. |
|
 Cred: 1096 | | My favorite device for ropes under 9.8mm. |
|
 Cred: 2643 | | Pretty good belay device for multi pitch. |
| Not as good as the BD ATC Guide |
|
 Cred: 22 | | very smooth, good for multipitch climbs, light weight |
| not for super big or small diameter ropes |
|
 Cred: 12 | | The extra loop is handy for releasing the auto-blocking feature. |
|
 Cred: 60 | | I just upgraded from the older Reverso. |
|
 Cred: 3 | | Really it's the easiest ATC I've used and it's the very light on the biceps. |
