Review on DEEWAZ Pressure Monitoring External Backlight by Charles Russell

I bought this unit to use with our caravan. (I know there are special units for vans. Our TT only has 4 wheels so we thought it might be worth a try). Less than 10 minutes after we left the house for our first ride with this TPMS system, a tire's reading dropped from 79 (good) to 16 (damn). We no longer thought the device was torn. and the tire was flat. However, there was no alarm, no icons on the screen and the color of the screen did not change from orange to red. So I'm glad it found our apartment in time to prevent further damage, but the device isn't quite suitable for this application and we'll return it when we get home. However, I will look into a TPMS from this manufacturer that will be better suited to our needs.
