Ordered TPMS the other week for my ute and caravan for a trip crossing the Nullabor. Package arrived within a couple of days. Fitted so easy. Did its job and told me three of the tyres on my ute were below what I set as the low alarm point! So off came the sensors and pumped up the tyres. And it still senses the caravan tyre pressures when the vehicles are parked over 20 metres apart (either side of the house)! Very pleased with this product.
