Zmoon TPMS Car Tire Pressure Monitoring System with Solar Power Universal Wireless LCD Display and 4 External Sensors Real-time Display 4 Tires' Pressure & Temperature

First thing: take directions & drop in trash can because the MORE you read them the MORE you’ll scratch your head and audibly mutter “wtf... are you kidding”? to yourself. These are hands down, the WORST, MOST confusing “directions” I’ve EVER encountered. They made me think of ME trying to write directions in Cantonese, that’s how awful they are. Remember, you’re NOT on a SpaceX mission to the moon; you’re only installing these lil gizmos on your valve stems & crossing your fingers that they work... that’s all. I took a deep breath and pretty readily figured out how to change display to PSI and Farenheit which is ALL I CARED ABOUT. I haven’t touched it since. I put on 4 rear tires of my RV and so far they’re proving to be helpful. But I’m not looking forward to finding/changing batteries; I’ll burn that bridge when I get to it.

I had a blow out on my camper which caused some damage to it. Delivered camper to the dealership and immediately ordered this product, not knowing camper would be at dealership for over 3 months for the repairs. Finally got camper back home and immediately installed sensors, the main unit picked the sensors up with in a minute of installation on the tire. All the sensors read close to the pressure i read on gauge except 1. I contacted seller and they replied quickly that they will ship out a replacement asap at no charge. Thank you Auto-Refitting Shop!!

Really easy to install, but make sure you do one cap at a time. I had two that had the wrong sticker on them and was reading incorrectly. Simple enough to fix though.They are decently accurate, but typically 2-5psi off. Still accurate enough to know if you've got a flat or low running tire.If you mount it, make sure it gets FULL sun, and be sure to fully charge it with cable beforehand.Mine was getting down to one bar of battery life so I moved it to full sun and it took 2-3 to fully charge again. Once it's charged, and kept in full sun, the battery life doesn't really drop at all.It's easy to see MOST of the time, but if you're at the wrong angle (too high, too low, etc.) it's hard to see...even at night. I'd recommend finding a place with full sun and proper angle if you plan on mounting.Overall I'd buy it again, as it's served its purpose for what I wanted it for and it's reasonably priced.

The sensors battery deplited without warning, i have changed them and everything back to notmal

These seem to work ok IF you can figure out how to install and set them up from the terrible so called instructions that come with them .

In order to protect the safety of the driver and passengers, the TPMS tire pressure monitoring system can immediately monitor tire leakage, excessive air pressure, high temperature. With six alert modes, you can take care of your driving safety anytime, anywhere. Suitable for passenger cars, off-road vehicles, commercial vehicles, MPV, SUV, minivans and trucks.

I like this external TPMS and it would certainly get the job done. I am curious how long it will last etc. If I notice anything worth mentioning down the road, I’ll update my review.What would make it better:1. Better instructions – Better explanation of the features and bigger than #2 font size2. Work in different frequencies to allow pairing with wider range of sensors - It only works in 433MHz, my 2012 Wrangler JK Rubicon sensors are 315MHz so there is no way to pair it.3. Have the lower TPMS alarm be less than 17 PSI. So I can deflate my tires when offroading without getting alerts.4. I wish the screen could tilt to allow for better viewing angleI made a video review.

This Tire Pressure Monitor asusten is great for any car. Easy to install and very useful. I have a car that has a TPMS but it doesn’t tell you which tire is low on air. This not only tells you the tire pressure, but it also tells you temperature. It can use solar energy so it can be mounted anywhere. It’s easy to use. I highly recommend it. I can see the benefit of using this on ATVs and other vehicles that you want to monitor tire pressure on.

these caps are huge. i wouldnt buy again. they make the wheels look bad

I received the item months after I ordered it and only 3 of the wheel sensors work. Honest review.

Verygood to have especially on winter tire wheels .

Stoped working after 2 months

Love the product but USB cord is too short for my needs
