Review on Low Pressure Liquid-Filled Water by Carlos Reyes

This is a nice easy to read gauge at a very good price. There is very little air inside so it's easy to read even at 50psi (12 hours). However, mine is off by more than 3psi at 30psi and 6psi at 50psi. I dropped the internal pressure and got no change. I've compared it to two other known good pressure gauges that read identical psi at two pressures. I was hoping for 3/2/3 accuracy ratings found elsewhere but was very disappointed. There's a reason a pressure gauge that looks so nice is so cheap. Mine was new in the box and well packaged although it may have been damaged in transit.
