Replying to How often do you have your bindings checked?

I'm debating on whether I should take my skis down to the shop and pay $15 for a binding check. This is only the second season for the skis and bindings so I'm not sure if it's necessary. In fact they were probably only used 15 times last season.

Do you guys get your bindings checked every season? or do you even get them checked at all? they're rossi Pro axial 100's (P10). They felt fine stepping in and out and when I moved the heel piece around.
