Sunsheln TPMS Tire Pressure Monitoring System Solar Power Universal Wireless Car Alarm System LCD Display with 4 External Sensors (Solar Power_External TPMS)

This little purchase gave me SO much peace of mind on our recent family trip with our new travel trailer. A tire blowout on a travel trailer can destroy the trailer and cause a terrible accident, so I was scared out of my mind about that happening to my family. Our trailer dealer said that we have to keep a close eye on our trailer tires and recommended a TPMS. I got on Amazon and found this - a little skeptical at first because it was solar and I wasn't sure if the distance from the unit to my trailer tires would work, but it works like charm. Just to be sure, we checked the tire pressure with a gauge after every few fillups and the tire gauge read almost exactly what the TPMS display said, within 1 PSI give or take. This is the one product I recommend to other people on the RV forums. By the way, there's NO getting these off without the little tool it comes with, so don't lose that

My biggest frustration is that it seems to reset often. It apparently resets because the battery is dead although the battery meter always shows full. When it resets it defaults to metric units and it's kind of a pain to switch it back to SAE.

Install pretty straightforwardYou can replace the batteries. Don't lose the custom tools that come with it!You do get readings for Temp and Pressure I will recommend it to my friends.

Safety for the price of knowing what's going on with your tiresIt a youtube on this item to program itIt does go off and reset itself a lot, but I find with that, i consider it to make me check on my tires.

Very nice, however it only came with Chinese instructions. It was also missing the part needed to change battery's in the caps. Otherwise works very good.

Sent a message to seller that instructions were in Chinese or something. I was sent a link that got me to a "Quick Start Guide", but had no detailed instructions on how to set the high and low limits for pressure or temperature, tire monitor positions, etc. Returning & will purchase a system where I can read and understand the instructions even if it costs more. I do not need aggravation in my life, the money saved is NOT worth it!

Cant read display on bright day, Sometimes it turns on and some times it don't, keeps changing temp and PSI back to Metric at different times and must change back.

its the beginning of summer and already the plastic melted, i cant use the buttons cause the plastic melted around themother thing, the pressure units change all the time from psi to bar.
