Really like this belay device - it's a very similar idea to the Gri Gri, but smaller, lighter, and with a simpler mechanism. Very easy and positive to use.

I occasionally have to feed rope if lowering someone lighter, and it can be touchy to lower someone heavy smoothly. It works up to 10.7mm, but works best at < 10mm.
