I see those are "not available" right now. I like the idea of solar power to keep the receiver/display charged, but am somewhat "offput" by the indication that they are from China. I wonder how much support you'd get from the vendor?

Also, it's not clear to me if you can add sensors. I have them on my tow vehicle as well as the trailer since having temperature monitoring seems a good idea during the additional stress of towing. Plus, having a pressure readout is better in my opinion than a dashboard idiot light.

I've had great luck with the folks at TireMinder. They even sent me three replacement sensors when the solder connections in mine broke due to battering caused by flexible rubber valve stems. I've corrected that issue, and note they are warning people about this problem, so I suspect they may not replace them anymore, but I thought this was fantastic support at the time.

Haven't tried them yet, but the reviews were good and the price was right. I decided to take a chance on it. My TV has pressure monitors already installed and I discovered that there have been issues with aftermarket monitors affecting the OEM sensors. I will put one on each tire on the trailer and one on the spare as well. Once I get them installed, I'll post a review of them.
