Super easy to operate and the auto locking feature provides a little extra piece of mind. Works well for rock and ice climbing.

I Like This So Much, I Bought Two

This is my favorite single-pitch sport belay device because it feeds ultra fast yet auto blocked pretty fast as well and it's very light weight.

Super Useful Assisted-belay Device

The assisted lowering feature of this belay device is super useful for experienced belayers. This device offers a really smooth experience, but beware allowing its use by the inexperienced, as I’ve seen it help people form bad habits.

Cheaper Alternative To Bd Pilot

Decent assisted belay device. The lowering action isn't as smooth as the Black Diamond Pilot, which I prefer over the Smart. The Smart is a nice belay device for the price.

Favorite Simple Belay Devide

I have been using this device for a long while now and it is my go to for my regular gym sessions. I've used it extensively for lead and found it's very easy to feed out slack and it locks reasonably well. Won't be quite as good as the gri-gri or pinch for falls but I haven't found that to be an issue.
