Tyler Mifflinwrote a review of Petzl Grigri + Belay Device on May 13, 2019
Familiarity: I've used it once or twice and have initial impressions
I have used the Grigri 2 for many years. I bought the new Petzl Grigri and it is so smooth and awesome. I have only used this one a couple of times. It is very easy to give slack, also very smooth lowering. The anti-panic stopping system is good for beginners or if you don't fully trust your belayer. It is nice to be able to switch between top rope and lead modes!
