Rated 5 out of 5 by from Works well; friction teeth are a nice option The friction teeth work very well. In fact, they work almost too well when belaying a lightweight climber (~115lb or less). You can always flip the device upside down and use the smooth end when belaying a lightweight person. Using that approach, the device acts more like a regular Black Diamond ATC.

Rated 5 out of 5 by from Favorite ATC EVER!!! This ATC is great! I have used it for everything from top rope to sport to using it when backing up another belayer. It's great whether indoors, outdoors, cold or hot. Anywhere my harness goes, this goes. It's been to Texas and Georgia and I will always trust my life with it : )

Rated 5 out of 5 by from Smooth belay and rappel I lost my petzl reverso belay tool and replaced it with this b.d.atc tool. Great trade up! This tool is very smooth but has great friction when it needs it.

Rated 5 out of 5 by from Great belay device I switched from a traditional style device with the two oval shaped holes to this one. Taking rope goes much more smoothly and I barely have to use any effort to lock it down for a catch or to hold someone for a rest. Great device and a mid range price.

Rated 5 out of 5 by from piece of cake My favorite manual ATC, there's not much of a difference between all of the manual ATC's but I like this one because the metal doesn't wear. Friction side is very good and usually not a lot of slip up.

Rated 2 out of 5 by from Bad design I bought this thinking it would be a great product but found the holes or slots for the rope where too small. It was a struggle everytime to get the rope into this device. Bad design

Rated 5 out of 5 by from Works like a charm The ease of putting the rope into the device as well as the way it grabs the rope when the climber is belaying. down

Rated 5 out of 5 by from Great ATC First time using an ATC instead of a figure-eight. Works well, durable, and has plenty of friction.
