TST 507 Tire Pressure Monitoring System, 2 Flow Thru Sensors for Metal Valve Stems by Truck System Technologies, TPMS for Caravans, Motorhomes and campervans

Product was exactly as advertised. And at better price than any I found.

Working as advertised, shipped on time. It even came with extra gaskets.

Quality product.

Great price ..... works and thats what matter, piece of mind

Works perfect Great Product.....

Use these on my toad. They all worked fine with my existing TST monitor. Removed the anti theft feature to make them smaller......( I remove them when in doubt....and when the trip is over). Also I dont program them in any special way as far as position....all I want is a warning if ANY tire goes low ANYWHERE on my RV + the toad............dont care which one (I plan to stop and look things over ASAP for ANY monitor warning. I have them on rubber valve stems (fairly short ones) on my Kia Soul ...... so far (2000 miles) no problems.....knock on wood.....dont want to have to install metal valve stems.

Well worth the money ,they work very well on my trailer.

EZ using new 770 monitor. Worked flawlessly on our toad pulled behind our RV.

Work fine.

I tow an expedition behind my Mountain Aire- they work great! I am within 1# of my digital gage. I didn’t put on security nuts. I remove when I unhook. Then check and air up before we start to tow again. I have a repeater on RV
