Review on 🚴 Bike Tire Inflator - Presta and Schrader Compatible Air Compressor Tool by Prestaflator by Kevin Singh

Bought after reading mostly positive reviews and thought it would be great for my new road bike with Presta valves. I got the unit, hooked it up to my 21 gallon 125 psi max compressor and was done with my tires. The first thing I noticed was that the device was deflating around the presta valve even when not inflated (and yes, I made sure it was in place and even checked out the product video). After being reasonably sure the tires were fully inflated, I unplugged the unit only to find that the gauge now reads 20psi without it even being plugged in. I tapped the gauge, gave it a swipe and it jumped from 10 to 22 psi but never went back to zero. When I attached the tire to my car tire to see if that would reset it, the gauge went up to 63psi, well above the tire's maximum pressure of 43psi. That's crap, the thermometer isn't zero. Stay away!
