Intuitive and simple!
- Familiarity: I've used it once or twice and have initial impressions
I I prefer it over the action of a grigri style device. It is a good device for rookie belayers as it is auto-assist for falls, and it makes lowering the climber easier and more fluid. Catching falls is smooth as the device does not lock up istantly.
One thing to note, it cannot be used for top-belay off an anchor. For that feature, go with the smart alpine.
