good items to consider from gmc
I have a system form tst, and like it.
I went with the flow through cells thinking it might make life easier since they would be inboard for the inner dual rear wheels. and I liked the idea of user replaceable batteries.
additional thoughts:
I found that the fish hook valve extensions on my outer rears would spin around from the weight of the sensor.
I bought some of the rubber grommet inserts to support the extensions through the wheels holes, and some long straight rigid extensions for the inners.... all to give better support for the sensors and for easier access.
With TST's the user replaceable sensors are toughted to have a battery life of approx 10 months, which seems about right
their sensors without replaceable batteries have a battery life measured in years they claim.
I regret buying the ones I did. i think I would rather have longer life, and with good valve extensions the flow through isn't much of an advantage.
