Review on TST Through Monitoring System Display by Travis Vasquez

3psi pressure gauge. an inch less than my other gauges show. The instructions are easy to follow. It took several attempts before one of the sensors registered on the display. Thought the battery might be bad. The screws were too tight to remove the battery cover. In the end it worked. In the sun, the display is not very bright. In general, it seemed to work well. Display lasts several days without recharging
