I bought one of these for each vehicle I have. I think the purchase was based on a recommendation I saw here in the forum. They are inexpensive, sturdy, and compact. No batteries required. They agree within 1 psi with the TMPS in my truck and RV. The TPMS in my GS always reads low relative to the gauge.
I have a BestRest gauge but the spokes interfere with getting it on the valve stem.
