Review on DEEWAZ Pressure Monitoring External Backlight by Ken Barnett

I had a cheap imported TPMS system on my truck because the manufacturer couldn't fit it on the car. After my tire broke due to a puncture, I had to install TPMS. At first I chose cheap imports, but it turned out to be almost impossible to read during the day. I decided to switch to something more readable and bought this device. When I went to install it, the previous device showed that my right front wheel had a pressure of 31 PSI. When I inflated all the tires prior to installing this unit, I found that the tire pressure was only 14psi! I knew the tire was deflating for a while, but I never knew it was that bad. The old TPMS didn't show a vacuum. After installing this block, we watched the pressure drop slowly over a couple of days and then took it to the tire center where they found a nail in the tire. I would most likely ruin another tire if I didn't install this block. It's so easy to read day or night. I highly recommend this device as it is accurate and the large easy to read display is a winner!
