This is the poorer man's gri-gri.
I personally hate this thing, I have used it quite a few times and it just strikes me as one of the more useless belay devices around.
On the down side: you can only use ropes from 10 to 11mm, the lockup is instant and cannot be controlled which makes it a terrible leader belay device, you need an HMS biner to be able to use it, it can hang up on the biner and hamper your belaying efforts... and I wouldn't want to get my finger caught in this thing, which could happen more easily than with most other belay devices(BDs). Self belay is possible but not as smooth as with other self-lockers.
On the good side: The only thing it's good for is belaying on toprope and it shines in this role... that is if you have all the requirements to make it work properly. this is the only reason I don't rate it a 1. Also it's impossible to thread it backwards and think you're doing anything right, better for beginners.
Bottom line: very specialized gear, use one and give serious thought about what you'll use it for before you buy it.
