Perfection.... the reading on my tires while parked in a hot basement for 4 days while I attended a training abroad.
I recently got this for my Innova, a Zeepin C260 TPMS for under P2k. It's totally wireless (with optional USB charging) and uses a built-in solar panel to recharge the internal battery.
The pressure readings agrees with my AccuTire MS-4021B digital pressure gauge to within half a PSI. I purposely bought the external-type sensor version because it affords the most flexibility when doing things like rotating the tires, transfering the sensor to the spare tire, or changing the sensor batteries.
The receiver automatically turns on when it senses vibration and shuts off 3 minutes after it stops sensing movement.
