Great idea! Valve damage doesn't happen as often off-road as tire damage, but when it does happen, I don't want to be without the Colbys!
I recommend the Emergency variant for quads, ATVs and all cars that do not have tools on board.
You can see how it works here in a video from Colby Valve or in a video from 4x4passion in which I show the installation of a Colby Valve Ultimate. Works with the Emergency according to the same principle, only manually.
