I bought this for my camper trailer. I had a few flat tires and got paranoid that I was going to be traveling with a flat tire and didn't know anything about it. Getting down to business, here are the pros and cons: Pros: 1. Installation was easy and painless2. He is accurate in his readings. We saw a sidewall tire lose pressure and we were able to stop in time to avoid tearing up my RV. Tymate sounded the alarm as the tire was rapidly deflating. Good work. Disadvantages: 1. The output is small. If the power connector is not in a convenient position to see the Tymate, it may be difficult to see.2. It took up to 3 hours for the tires to stop flashing and start reading. It may have read the exact print, but the blinking led me to believe it wasn't working. After about 3 hours on the road, the last tire finally stopped flashing. I haven't found a way to display the temperature in anything other than Celsius. The pressure is shown in psi but not the temperature (at least I couldn't do it and couldn't find anything in the manual how to do it). Overall it has alarms and does what it's supposed to do.
