I have the flow-through sensors and if any went bad I would replace them with the standard sensors. The flow-through allow such a small flow of air that it takes a substantial amount of time just to add 5 psi to a 16" trailer tire.
I find that I take the darned things off to add more than a pound or two as it just takes so long to work with the flow-through. Not worth the hassle IMO.
Just my opinion doncha know.
