If you think the grigri by Petzl never fails, think again! It is a very reliable device to belay a climber with a hand on the break side of the rope. But please be careful if you want to use it for Rope Solo Climbing!! Note that a chest harness can make it worse.

the GG 2019 fails with a Beal Booster III 9.7mm rope
