Review by deathbybowtie on Sep. 07, 2011
Great grip strength. I like the teeth better than those on the Petzl Ascension, they're less sharp and seem like they'd be friendlier to the rope. The clip-in loop at the bottom is huge, which is pretty convenient for getting a carabiner's gate all the way through. There are several ways to actuate the trigger, which can be handy.
I ran into more than one situation where the cam opens too easily, and if I hadn't had a carabiner on top my rope could've easily fallen out of the ascender. If pushed too close to an anchor point, they can be very difficult to remove from the rope. Heavier than the Petzl Ascension, and they require more weight below them to move up the rope without using the trigger. I find them prone to binding if not pushed up the rope perfectly straight.
Petzl Ascension, prussik knots in a pinch

Innovative construction holds to muddy ropes better than others. Attachment points all over the place.
Kind of bulky and heavy. Opening the cam sucks, its really awkward and annoying.
Petzl Ascension is way better.

True out of the box thinking. Unique 4-bar system increases grip. Excels in ice and mud.
Heavier than Petzl Ascension.

The 4 bar system does not only increase grip it also saves the rope - think about it - it would work even without the little spikes.
You got a small hand, you got a bit of a problem.
