Bruce A.wrote a review of G3 ION 12 Binding with Brakes on December 27, 2016
Familiarity: I've put it through the wringer
I have 20 or so days on this binding with a mixture of ski mountaineering, backcountry and resort use.
Construction seems solid, good ski crampon attachment and I can install crampons with the ski on if needed. Tours well on the flats. Good ski brakes.
Difficult to change to ski mode with the ski on compared to my Dynafits, and must remove ski to change back to tour mode. Highest climbing aid is not high enough for steeper ski tracks.
The heel rotates a bit on each turn on hard snow which makes the ski feel like it has a big base bevel. Same ski with alpine bindings skis with way more energy and rebound.
I have skied some really steep hard snow, no fall zones, ski resort bumps all with no pre-release, and at this point no hesitation to charge.
I'll be looking at the Fritschi with lateral toe release for the next setup.
