I have one of these. I highly reccomend it. It is the Cadillac of fall restraint belts. Everyone in my climbing class was skeptical of it, but we all came to love the system and trust it. A lot of us prefer it over the Synch-lok. The cleats on this system will always catch you during a fall. (as long as the system is adjusted properly). Like i said, it is the Cadillac of the fall restraint belts. Ascending, descending, and circling the pole is an absolute dream with this thing. It almost feels like youre only climbing with a leather strap. Smoother (and in my opinion) a much better alternative to a Bucksqueeze or a Synch-Lok. Its also $300-$500 cheaper. Highly reccomended.
I've been climbing for more than 30 years and I have to say that I do agree that this gear is smooth, comfortable and easy to climb with. Well thought out design. Love the blade type cleats where is slides around the pole while circling, and the convex shape are like 4 cleats cutting into the pole immediately replacing your 2 gaffs in the event of cut out. Also, the smooth and easy connection with the snap hook and adjuster eye is "golden". Access to release lever with the thumb is beautiful. Simple, elegant, effortless. Try it out.
