We have had TireTraker system for a couple of years. No pass though inflation and user replaceable batteries. The only problems I've had was a failed monitor replaced under warranty and an occasional loss of signal, usually on one of the rear dual tires or on the Jeep tow'd. Once it was a battery failure. Not sure what caused the others, but I stop when convenient and remove/replace the sensor and problem fixed. Have not had to reprogram although I have had to do that after rotating tires on the Jeep. No big deal with TireTraker.
