Tire Pressure Monitoring System 7 Alarm Modes Solar/USB Charge TPMS with 6 External Sensor 1 Signal Repeater ( 85ft Sensing Distance ) for RV Travel Trailer Motor Home Truck(0~199 PSI, -40~257℉)

The product sets up easy and works as advertised. No complaints there.During setup and at the start of the first drive with the TPMS, I was wearing my regular glasses. Nice bright display, very visible. About an hour into the drive, I realized I was not wearing my sunglasses and changed. Shortly after, I looked at the TPMS and the display was black. Nothing, nil, nada. First thought is the display crapped out. Luckily I turned my head before I entered full p/o mode and saw a bit of the display. Turns out the polarization of the display is exactly opposite that of my sunglasses. With sunglasses on and the display horizontal (normal), it appears black. Putting the unit in any other orientation, preferably vertical, everything is visible. This has been tested with multiple pairs of polarized glasses and all yield the same results. So, if you wear polarized sunglasses, you may want to avoid this unit. Other than this, it is a great unit and has already caught a leaking tire.

I have been using the 6 TPMS for my RV for one week.As of now everything works great. It's certainly nice to always see my tire pressure in real time, especially driving a large rig.Setup is easy. The valve sensors work when the tires start moving so it doesn't waste battery. The display is smaller than expected but I like that. The sticky display holder works great for now and is movable.4-5 stars for the functionality and ease of use. 1 Star off for the display because it does seem kinda cheap/light plastic and it's hard to read at steep angles.Would recommend depending on lifespan.

Instructions are awful. I finally got it installed after watching some videos. Tested. Seemed OK.

Unsure it will work towing my 38’ 5th wheelThe extender will not connectAnd is hooked to 12 voltsFrom the axels to the cab of the truckIs only 20’Heading on a road trip soon hope it worksUPDATE :was contacted by the sellerAnd was offered a refundThat’s great customer service 👍👍

5 out of 6 worked. We bought this for a road trip in our rv. Hard to read the screen while driving and had one out of the six that didn't work.

The media could not be loaded.  I'm using this to keep an eye on my trailer during an upcoming trip. It was easy to install, and gave readings very close to my digital pressure gauge. Setting custom high/low pressure warnings was also straightforward.While traveling with the display on the dashboard, I couldn't get readings for the back (farthest) tires so I used the repeater and that took care of all weak signal problems. So with that minor problem solved, it gave frequent updates for all trailer tires, and it is easy to put it wherever you want because it has no wires. The solar panel on it seems to be sufficient to keep it charged while driving around in the daytime.Since I am mostly interested in knowing if I have a flat and the low pressure alarm is sufficient for that purpose as long as it is getting good data from the sensors. I don't need to constantly know exactly what PSI the tires are at if it will just warn me that one is leaking. Overall a good purchase for the peace of mind knowing I'm not driving along unaware I have a flat on the trailer until it blows up.

There is no telling how many of these units are returned because the make believe English doesn’t tell you about the abort/destruct button on the display unit.When you receive the unit you need to look on the back of the display for a small slide switch that turns it on. From then on you hold down the left control button on top for 6 seconds to turn it on and off.If you use the slider button on the back and turn it off……..your done. You will have to reinstall from the start.My hard to reach duel rear wheels on a motor home were installed 4 times before I figured it out.If this works I will give it 5 stars even after the frustration I experienced.

Should come with valve extenders to make install easier, but other than that it works great! I pt them on my motor home and did not need to use the power booster.
