Eric Henricksonwrote a review of G3 ION 12 Binding on January 10, 2018
Familiarity: I've used it several times
The bindings themselves are great, minus the fact that they are being recalled by G3. There is another issue, which is the heel screws. The screws are larger than the toe unit screws and not tapered. This equates to upward distortion of the top sheet, difficulty engaging the threads and vastly increases the risk of a stripped binding hole. I have mounted many sets of bindings and never before had a binding screw hole stripped. This happened twice in two mounts despite approximately 100 pounds of down force to persuade the threads to engage and follow themselves. I am not sure what made G3 believe that they should have two different screw designs for one binding, and why they chose to deviate from the industry norm, but it was not well thought out.
