GT40 Solar TPMS with 4 Sensors

This is my second TPMS monitoring system and I am quite impressed compared to the other, cheaper one. The reason for five stars is that compared to the other one, this one connects to the sensor is much faster, is actually within one PSI based off my quality snap on tire pressure gauge, and the biggest thing is that it refreshes each sensor much quicker than the cheaper one. Within about a minute it has cycle through all the sensors and its sudden pressure loss indication is close to instantaneous. It also has gone the distance chargewise as we recently took an 8 hour drive, half of which was at night and the battery lasted the whole trip. Definitely worth the extra few dollars that this will cost you.

I love seeing all tire pressures even my two spares. I wish the readout wasn't "trailer" related. I use this device on my Mercedes Sprinter 3500 RV, two front wheels, four rear dually wheels. I have two spares.

Has worked flawlessly so for and was easy to install.

Works great for keeping track of trailer tires pressure

Works as described and very happy with the performance! The pressures are within 2 psi of my digital tire pressure gauge, which is a non-issue. Gives peace of mind when towIng my RV. Quality materials and easy to install. No programming required, they're plug n play.

I'm happy with it so far so good

Installed this on our travel trailer. It Worked perfectly on our latest 2,600 mile trip. No leakage. No connection issues.

Product has worked perfect and has been comforting making long trips towing at night and not being able to see tires in the mirrors. This allows me to know they’re in good shape. I had a tire go down and the working alarm on this product let me know right away. Battery on this thing will keep it going all night long. Only downside is the sensors are heavy. So I would recommend getting heavy duty (metal) valve stems at your next tire change.
