  A heavy, but rugged tube style device This device is very heavy compared to its competitors, but it is MUCH tougher. This is a great workhorse device.

  Light and cool Heat dispersion is great. Won’t burn your hand off after a quick belay or rappel.

  Needed a belay device for Needed a belay device for skinny ropes and the Alpine Belay fits the bill. Works well with thick ropes to but isn't quite as smooth as an ATC. Works surprisingly well on frozen ropes.

  Great design, easy to use! Essentially it is an ATC, however, with the structure and material, it is stronger, better looking, and can also be used in the alpine situation. Definitely recommend this item if you are thinking to have an ATC for your either climbing or alpine trip.

  Does what it says on Does what it says on the tin. Because the loop is full metal instead of plastic-wrapped wire, it does occasionally make noise hanging off your harness. If you are participating in a tactical assault against a fortress on a hill, this may reveal your location.

  Leichtes und anwendungsfreundliches Gerät Genutzt beim Nachholen und sichern des Nachsteigers. Sehr zu empfehlen beim Felsklettern.

  the cyberpunk belay! i love this device so much! provides a reliable aount of friction, its as light as the petzl belay, and with the steel inserts will last a thousand lowers more than the petzl. I clip my HMS into one of the tubes in the device like im using it like a rigging plate, and that makes it lay flat flat flat on my harness. same price as the BD version and a million times better, and y

  Nordwand Alpin Belay Light, robust for various usage (lead, repelling, belaying). Works better with narrow ropes. Nice looking too.

  Great I used this as my belay device for multi-pitch climbs with a 9. 5mm rope, and it worked like a charm. So light I had to check it was still on my harness, yet the steel wear points are super durable. I would not recommend it for a gym climber, or someone who prefers thicker ropes. It is not designed for that use and doesn't feed very smoothly with ropes +10mm.

  Must have for multi pitches This belay device never leaves my harness. It’s simplistic and light. The ascend mode is also must need knowledge for any kind of adventure climbing. It will get you out of many sticky situations. I always put it on an extended rappel. Works good with my Mammut rope and doesn’t have too much friction. I’m a lighter climber and I can rappel without too much feeding. Easy

  Great little belay / rappelling device for small diameter ropes Bought this to replace my worn Reverso. I specifically wanted a guide style ATC to pair with my 9. 0mm alpine rope. Have belayed with this device from a top anchor in guide mode, rappelled, and used as an ascender. It works great, no complaints. For this combination of device and rope it provides just the right amount of friction bela

  Great Purchase! The fact that it is made of steel for the most part is priceless! it lasts a lifetime.

  Versatile and durable device I've used the Reverso and the ATC for years, but decided to get the Alpine Belay this season as my previous device worn out. I'm very happy with it. Functionally, it does what you expect from this category of devices. It works very well with single and double ropes (I've used 8.5 through 9.5mm), has a well balanced catch when lead belaying and just the right amount of

  Perfect do everything ATC I have a BD ATC Guide and a BD ATC Alpine Guide. They are both great but I always have to think about what diameter rope I am bringing. This ATC from Mammut comfortably handles ropes from 7.5mm to 10.5mm. No more pairing belay devices with ropes.
