Very comfortable
"The device works as expected. I haven't had the rope slip on me at all, and not having to put so much force into holding the rope is nice, especially on longer belay sessions. The difference between the smart and other geometrically assisted devices is that is is very comfortable to hold. It is larger and has rubber cushion on the handle which make it easy to grip and prevents the device from digging into your hand when braking or lowering."
