Tire Pressure Monitoring System, RV/Trailler TPMS with Solar Charging & Auto Calibration, M13 LCD Display tpms 4 sensors (0-87PSI)

Just used this on trailer tires for a short road trip while pulling a boat on a double axle trailer. It gave me extra peace of mind knowing there were no tire issues. One time in the past I did have a flat and didn’t even know it until getting home. It was lucky I had no accidents or related damage, but this device will help prevent that scenario. We will see how it holds up to the sensors being dipped in salt water at the boat ramp over time. I know someone else who has done it a few times with this exact product and so far it’s been fine.

Overall, I think I am going to like this device. I have one tire that is losing air, so I will test this unit in this condition until I buy a new tire in a few weeks.(1) Instructions should advise to plug in the USB cable and then find a good place on the windshield to attach. You have to leave room for the USB connector in case you need to charge it (e.g., car parked out of sunlight most of the time).(2) I pressed Set for 3+ seconds, but not sure if the air pressures and pairings are "set". Display did not change in any way. I would prefer an icon to show Pairing vs Set.(3) Pressures appear to be accurate. I used my VEEAPE Air Compressor Portable Tire Inflator to get them all to 34 psi, as two were already at that pressure. Readings are 34 or 33 psi in each tire.(4) Unit has not turned off yet. I will check again in the morning.

I wanted to have a reading on my trailer tires and saw this product. Read some reviews and thought I would still give it a try. Very easy to read the size is good and the solar power is nice to have for long trips. Although I don't use it a lot it is nice to know the pressure and temp of the tires on the travel trailer. The sensors use a battery and I only needed 2 so I have 2 backups. I wasn't sure about the lock system but they work, it took a bit to get them off. Once you read the manual it makes more sense. I had it on bar and it took me awhile to figure it out and got it back to psi. The sensors do work well and easy to use, it does take a second or 2 to get reading, but the piece of mind is worth the money.

Easy to install. A lot of peace of mind for my RV because nearly all trailer tires are made in China and their quality doesn’t have very good reviews. One sensor took an extra 3 or 4 minutes to display but worked perfectly after that. It’s a good product and the peace of mind is well worth the price.

Why Honda did not include real-time tire pressure monitoring from the factory is beyond me. Had this product on for almost a year and it’s great. I have it mounted on the very upper left edge of my windshield. Doesn’t obstruct my field of vision and not too bright to be distracting at night. The fact that it’s solar powered is great. I live in Texas, so I’ll always have scorching bright light. So far the readings have been accurate (I double check with a digital pressure gauge). The big knobs on the valve stems look ugly, but it’s a small price to pay for peace of mind. Would recommend.

We’re currently at the end of our first trip with them on our toy hauler. They definitely worked! We had a low pressure alert not far into our trip. Thankfully we were able to air up the tire and continue. We received a low temperature alert later into our trip but we were going through some cold rain so it wasn’t a concern, but it was good to know they work!!

Really cool Tire Pressure Monitoring System (TPMS)! Installation was a breeze. I pre-charged the monitor in advance at home, the previous night before placing it in my truck, using a standard USB-C cable. The next day I simply screwed on all the sensors, following the correct tire indicator. In my case I did not have to pair anything as everything simply came on. I even removed a couple of the sensors on purpose, just to get a sense of the alarm type, level, and indication on the monitor screen. It wasn't obnoxiously loud as some have reported, but it doesn't stop beeping. I stuck the monitor itself to the lower left-hand corner of the windshield, just above the dashboard and to the side. Out of the way but still easy to spot and read. The most important thing is that the air pressure measurements are very accurate! I almost always check all four tires of any car or truck I drive before entering the vehicle, but this little gadget will give me a peace of mind. As soon as you enter the vehicle, the screen wakes up and you can see all four tires air pressure and temperature at a glance. Buy this thing!

Only one side sensors display correctly — the other two never show any readings. It looks well-made, but the actual performance is really disappointing. I rarely leave one-star reviews, but this product truly deserves it. I would not recommend it.
