The Edelrid Giga Jul combines assisted braking, standard tube-style use ("manual" mode), and auto-blocking all in one single device. Combining these three different modes allows for a nearly endless number of options when lead belaying, belaying the second, or rappelling, making this the most versatile device we have used. Switching between the various modes is as easy as simply flipping a slider from one side to the other and loading the rope in the opposite direction (there are pictorial markings on the device to ensure the device is loaded correctly). We love having assisted braking for lead belaying, even on multi-pitch climbs, and especially when there is some chance the leader may fall, and the Giga Jul allows us not to have to carry a second device for this purpose. Its weight and bulk make it slightly less appealing for long and difficult climbs or those with long approaches.
