Review on Accutire MS 4021R Digital Pressure Gauge by Isaac Cahill

I've had an earlier version of this for many years. They appear to be identical except for the color of the rubber grip. Except. ;) In the old version there was no backlight for the LED. You pressed the valve stem and the pressure gauge showed pressure. If it was dark, you need a flashlight. OK, I can live with that. Now I buy a new version and press on the valve stem. And he doesn't read anything. The? I start investigating it and find a small button that I now have to press that wasn't there in the old version. It includes an LED indicator and glows, so you don't need a flashlight in the dark. I think there was a manual that said that, but as a man I haven't read it. Overall it works as intended. If it lasts like the old one, 10-15 years, it will be great. I don't think you can go wrong with that.
