After just over a month of use, I would not recommend this product for the following reasons.1. Tire pressure and temperature difficult to read. In strong sunlight, the display is completely darkened.2. When I first installed four sensors, one didn't respond. I think the battery in this sensor is dying fast. The funny thing is that there was exactly one extra battery in the kit. So it worked after I replaced the empty one with a spare. A few weeks later, some of them were very slow to respond, taking over 20 minutes to see the first reading. Exactly 40 days after installation, these two are completely discharged and the battery voltage is below 2.65V.
