Joshua Moorewrote a review of Black Diamond Big Air XP Package on July 29, 2019
Familiarity: I've put it through the wringer
The ATC-XP by Black Diamond is the go-to tube style belay device for any climber. I prefer the XP rather than the regular old ATC because of the added friction for the brake hand. It is super simple to lower, and I'd recommend this device for all beginners.
It is really easy to use for rappelling as well.
