Tried and True

  • Familiarity: I've put it through the wringer

I've been using the same style belay device ever since I began climbing and the Mammunt crag light belay is basically a lighter version of the same. Not a factor unless taking into account overall weight of your climbing rack. For performance this ATC is an easy to use, reliable piece that wont cause any unnecessary hang ups while still providing the friction needed to keep the rope stable and slip free!

Great Choice

  • Familiarity: I've used it several times

I bought this belay device after using similar designs by other companies, and I'm sure glad I did. I would recommend this device for anyone first starting out climbing because it really holds the rope tight when in the brake position. At times it is hard to feed slack for top rope, but this makes the belayer become more cognizant of their actual belaying techniques. I have only used in the gym, but it does a good job at what it was designed for. It feels like it weighs nothing, but is completely solid. I want to try different thickness of ropes as well as other applications, will update later.

Solid protection

Got this ATC with the Mammut crag pack found here: http://www.backcountry.com/mammut-crag-bag-kit

Nice and light. Smooth feeding for the most part but the teeth can make for a jerky lower on some twisted ropes, although they do help hold catches, which is worth the trouble.

New Favorite

  • Familiarity: I've used it several times

This is my new favorite belay device! I have four tube-style belays that I share around when I take people climbing, but I tend to use this one myself. It is light and easy to load. My ropes are 10.1 and 9.8 (Sterling) and they slide well in this device but brake easily as well.

I use this for rappelling and belaying top rope climbers. Almost all of the people I belay are heavier than me, so I love having the teeth to assist my stop. As a lighter climber, I also like the option to turn the device around and use the other side for a quicker rappel.

Very grippy

Awesome belay device when your climbing buddy is heavier or your rope is a bit skinnier. Teeth really grab the rope. Can be too much friction for larger ropes or if your partner is on the lighter side.

Great Belay Device

I've had one of these for a couple years now and it's held up incredibly well. As far as simple tube-style belay devices go, this one is solid, not too heavy, and does a great job braking on the rope. It's also a couple dollars cheaper than comparable belay devices, which is always a plus.
