because of the mixed reviews i bought the reverso3 and the atc-guide at the same time so my boyfriend and i would both have an atc and then we could compare them and see which was best for us- we're both beginners and climb at the local gym so we haven't been able to use all of their features, but they both belay very well- particularly when using the friction side-

i do prefer the reverso3 over the atc-guide because the reverso3 will take the thicker ropes that my gym hasn't changed yet-

it is not important to note but the reverso3 is considerably lightly than the atc-guide- when we are able to purchase our own ropes and go outdoors i can leave a more thorough commentary on the reverso3-

This is probably one of the quickest and easiest to use products i own. The design is great and it's very light weight. It locks off well for rappelling or lowering and functions great as a lead belay. It also hangs very well on a top anchor for a locking belay when climbing multi-pitch. My climbing partner and I both own them. I have not used it on double ropes, but friends tell me it works great on skinny ropes as well. Out of all the belay devices i've used and owned, this has by far been the best. And it comes in cool colors!! Definitely recommended to climbers of all levels.

One of the best belay devices on the market today. It feeds out rope smoothly and easily and locks quickly to catch that unnexpected fall. When bringing up a second or two, the ropes feed easily with little to no binding allowing you to concetrate on your partners progress. on autolock mode, the rope cinches tighly and quickly. Using a carabiner, one can slip the oprn gate into the device to allow one to lower with ease (something that the BD ATC fell a bit short on). The device can be a little less smooth on rappel, but I opt to turn the Reverso 3 around so the teeth are away from my brake hand (*not something the company recommends) and I have had no problems with binding or seizing on the way down. Overall, a great device for the money. The Reverso 3's ligthweight design and solid performance has earned a permanent place on my rack!

A little jerky on rappel but great on belay. Did not seam to bind up like my ATC tends to on lead. We've only used it single pitch sport but it functioned super smooth with the 10.5mm Accelerator. Only complaint is no one can get it in green...

The Reverso³ offers a wide range of functions: Belaying the leader or one or two the second climbers (in self breaking mode, if you like), using a single rope (from 8.9mm to 10.5mm (11mm accepted)) or half/twin ropes (from 7.5mm). So compared to other tubers with the same range of functions it can handle thinner ropes, and it is also lighter.
It's the most complete (not self locking) belay device I ever got my hands on.
