My biggest complaint with these is that I broke to sets of them within a year.
Once I landed 90 coming off a rail, caught an edge and snap. The back piece broke at the base. The other time I came off a rail switch, landed and boom. The back plastic mounts that hold the back mechanism in place blew up. I'm a big guy, but bindings shouldn't be blowing up like this.
They released when they should and stayed on when should. I have no complaints there. However, it is the durability of the plastic pieces that has caused me to never buy marker bindings again.
