It may sound sketch, but the binding is secure on the track and after several years, I have never heard of the cam lock releasing. I have heard of a need to occasionally check forward pressure indicator. The binding remains an upper level Marker recreational binding, so if that is a problem for you, these skis are not your thing.
I have never heard of a release check failure on new equipment properly set up. I consider it a complete waste of money and time to drop off skis at a shop and have them torque test them. Especially true, because on these system skis, we constantly change the settings and sizes. Whatever floats your boat for peace of mind, but IMO If you have any idea at all what you are doing (sole condition, alignment, forward pressure), all this release check stuff is induced by real liability concerns by shop owners and techs (they have to check). Since you are unlikely to sue yourself for negligence, you can probably make these adjustments and be 99.99% certain that the release settings are a decent approximation of the DIN shown on the binding. If in doubt error to the lower DIN side like the shop does.
