Colin Clancywrote a review of Petzl Grigri 2 Belay Device on June 15, 2017
Familiarity: I've used it once or twice and have initial impressions
I've always used an ATC-style belay device, and I'm so pumped that I've now switched to a GriGri. It's so simple to use and makes belaying so much easier. LOVE IT.
