Herb Colbywrote a review of G3 ION 12 Binding on March 22, 2018
Familiarity: I've put it through the wringer
Ion 12 bindings worked well for a season, then after adjustment to fit new boots, the heel turrets would not remain in tour mode. Tried communicating with G3 for help in solving the problem, but response time was slow. Bindings eventually sent to G3. Bindings have been at G3 for > 2 months, with no meaningful information coming from them about findings, status, or plans to fix/replace/return. In the meantime, winter is slipping away. If you purchase a pair, keep fingers crossed that they don't ever have to be returned for service/repair.
