Took this out on a multi-pitch last weekend and it handled both rope strands without any fuss. The rappel mode feels smooth and controlled, and it's genuinely the lightest device I've clipped to my harness.

Took this on a multi-pitch last weekend and barely noticed the weight on my harness. Handles a single strand smoothly on rappels too, which I didn't expect from something this tiny.

The lightweight build is nice on long rappels, but feeding two rope strands through it takes more effort than I'd like. It works fine for single-strand belaying, just don't expect it to be the smoothest device out there.
