Don't know how good it will be but for 20 bucks I'll take a chance and ordered it. I will write a review as soon as I get it and can use it on my trailer.

I had one on my Scamp and it worked fine. Since it has monitors for 4 tires, I placed the extra two on my spare tires on the Scamp and the tow vehicle.
Started down the driveway last month on a trip and the alarm sounded as I began moving. Checked the guilty tire and found a nail in it that I had to remove, but better to notice it in our driveway than on the highway.

Only potential issue for some is it is limited to 3.5 bar which is ~ = to 51 PSI. I keep my tires at 50 PSI or less, so it should be OK.

I did a pretrip pressure check one time: 41 PSI tire 1, 41 PSI tire 2, 40 PSI tire 3, 8 PSI tire 4. What? Changed it in my driveway.

I have a similar one (different brand name but otherwise identical) that's worked well enough for a couple years or so. I think I paid more like $30.

Think positive. I bought a $35 back up camera expecting to replace it with something better in a year or so. That was 5 years ago.
