Beipuit Wireless Tire Pressure Monitoring System (TPMS), with 4 External Cap Sensors (Cigarette Lighter Plug with 5V/1.5A Charging)

I ordered a similar product from another manufacturer than came with poorly written instructions and the unit was faulty. I reluctantly decided to try again. This model was easier to understand and worked perfectly the first time I installed. After a month of daily use, my monitor still functions excellent. The sun keeps the unit fully charged and there is no need to plug it in.

We have a 36 ft. Class A RV with tow dolly and car in tow. A flat tire on the tow dolly or rear wheels of the car cannot be felt when driving the RV. I placed front sensors on the dolly and rear sensors on the car rear wheels, and the display on the RV dash. With the display on the windshield at eye-level, there were no issues with signal reception from the towed car and dolly. Very good value for peace of mind.

I have a travel trailer that I am using this system on. I set up the sensors as described in the instructions and everything worked just fine. All 4 tires showed the pressure and temperature for each on the monitor.The only problem was that the system had to be reset to fix an issue with an EE 00 message that would show every 10 or 15 seconds then go back to the main display. The vendor quickly responded with a solution to the issue. Since I reset the monitor the TPMS system works great.I have a 30 foot trailer and use the monitor from my pickup truck cab. I have no problem monitoring the trailer tires from that distance. The solar panel keeps the battery charged when sunny too. You can spend much more for a TPMS monitor that doesn't offer much more accuracy and long range monitoring than this.A bonus is that you can purchase replacement tire sensors if you damage or lose one.David at Beipuit Customer Support, quickly responded and also followed up to make sure that everything was working fine. Excellent customer support!

Within one month of purchasing this item it practically saved me from a flat. I was at a gas station and 1 tire was registering 2 psi lower than the others. I thought nothing of it at 1st till I left the gas station.I was on the service road by the time I got on the ramp the alarm started going off on the sensor. I looked over at it and the pressure was dropping rapidly on that 1 tire. I quickly pulled over and stopped, by the time I stopped I had a flat tire. I took it to cowser tire company and they said it could not be repaired and that I was lucky I did not have a blow out it would have been badd.

Just got this unit to replace another two year old unit from a different make which stopped charging. I use it with my winter set of wheels, so much cheaper than getting OEM transmitters which are too expensive to program. The aluminum wheels I'm using it on are almost 11 years and the paint started to flake from oxidation even though I clean them and wax them. The salt will still get to it. Anyhow, it recently detected a slow leak and when I pulled off the wheel, I did not see any visible punctures and no bubbling from the valve stem seat. Dropped it off at the shop and they said it was slowly leaking where the tire bead meets the rim. The garage sanded the rim smoothly and I'm good again. The unit was able to tell me that the tire had lost air compared to the other 3. So, it saved me from having a flat out on the open road. Better than my old unit because it has alarms and shows temp in Fahrenheit. Important thing is that it is inexpensive and cheaper to maintain or replace altogether.

Had the VeSafe model installed for a couple years and it was a pain. It wouldn't hold charge and when removing the sensors they almost always broke. New sensors cost nearly as much as this entire TPMS kit so when it was time to replace a third VeSafe sensor I upgraded to this model.The battery life on this monitor is amazing. The indoor receiver is slightly larger than the VeSafe making the display much easier to read. It gives an audio alert if there is a problem with a voice literally telling you what is wrong.Sensor sensitivity is very high. When the tires are warm the monitor displays the higher air pressure and temperature. On my 37" x 12" on 18" wheeled tires numbers can be exactly the same and fluctuate while driving my as much as 4 psi within each other tire with temperatures sometimes ranging a little more.These sensors are pretty much identical to the old VeSafe sensors so hopefully there won't be any problems. This one seems to be easier to calibrate. Haven't yet had to rotate these sensors with the tires though they've been on a few months. I would almost certainly purchase this model again. Kind of wish I had more for each trailer we tow.

I love it,the product is wonderful and I continually have information about my tires, just that the precision is not very exact with my mechanic I measure the pressure of the tires and it marks 32 psi but in the tpm 28 psi

Item works as intended, sometimes you need to firmly push it into the cigarrette lighter if it's not reading.By default, the monitoring system goes by a different measurement scale, the instructions are easy to follow, I just changed it to the correct settings for my tire pressures and the temperature.The caps are not deeply threaded. So curiously, they look easy to steal. Surprisingly they don't come off easy. You'll need to use the provided tools.Long term, my tip is to get a small zip bag and keep the tools in your glove box and a 4 pack lithium battery. I forget what size.Here's a true side story, a TPMS saved my life/passengers/car/tires 2 Christmas eves ago. My rear passenger tire pressure quickly dropped from 29 psi to 19 psi within a matter of minutes. I was highway driving nearly 75 miles an hour in the Chicago snow. The bright orange light was hard to ignore.Long story short... I pulled into the closest gas station. By that time, my tire pressure read 0 psi. That was a 2016 model car with a factory installed TPMS. And it saved me from what could have been.I recently bought an older model without a factory TPMS and it's worth my life to pay 2 quarters and a dime of a hundred for this. I highly recommend it if you drive a car without one. It could save yours.
