I bought one of the “knockoff” TPMS tools last August and have yet to take it out of the box - although it’s made 3 trips to MA to program my son’s TPMS sensors ... and each time we forgot to do it! LOL! To make matters worse, he just replaced all 4 tires from Tire Rack and Firestone charged him $190 to put them on! And he forgot to change the TPMS sensors - one of which is definitely dead! 😩the CORRECT way to do it. lay the device flat on tire wall- with antenna tip very close/touching the valve stem.
Those are my hands and our now sold Impala.
