Review on 📏 Digital Presta and Schrader Pressure Gauge: SKS Airchecker by Michael Rosario

I put it off after I first got it because it never worked for us. Today after watching other people's videos I see that it just never worked. It holds no pressure reading when you remove it from the valve, the reading returns to 0 once the pressure gauge is removed. It doesn't beep when it reaches the final reading, although the final reading can be somewhat estimated as you watch the reading on the display increase for a second or two and then the reading decrease as all the air is deflated from the tire becomes. . It doesn't beep when it's on, as seen in videos from other users. This applies to both Presta valves and Schrader valves. The backlit display is nice and bright, but not very informative. Too late for replacement?
