Review on 🌡️ Winters Economical Pressure Internals: Enhanced Test, Measurement & Inspection for Pressure & Vacuum by John Bennett

When my first one arrived it read 7psi out of the box. I didn't even plug it in. I contacted Revain for a replacement. This is used in a build that allows me to raise/lower two tires at once. We ride off-road and being able to bleed two tires at the same time is a good thing. It also allows me to equalize the pressure between the two tires. I also have the option of checking the line pressure with a regular tire pressure gauge (just a fallback). I have one electronic and two manual gauges that I use. All three showed the same readings at 40-65 psi. The replacement pressure gauge arrived two days later. This was at 0 PSI out of the box. I installed it and started testing. I thought that at this price point the pressure gauge would be way off. In fact, what I found after testing with three of my tire gauges was impressive. At 40 psi and below it is about 1 psi. At 50-65 it reads to the nearest 1/2 psi. I used high quality, expensive, oil filled gauges that weren't that accurate. Result. I am very happy with the replacement and glad I went with the same brand/seller etc. Thanks very much!
