Review on 🔧 CZC AUTO 2-in-1 Digital Tire Pressure Gauge Reader Checker with Backlit LCD - Accurate PSI Gauge for Car Truck Bicycle Motorcycle - Tread Depth Gauge, Non-Slip Grip, 0-100 PSI by Craig Kumar

Pretty good for $11. Not sure how to make money on a $11 product with uC, pressure sensor, LCD, PCB and software? Works well, software detects activity (usage) to maintain power, but automatically turns off when usage ends. Short press the power button to turn it on. Holding the button for 2-3 seconds also turns it off. You'll have to figure out how to position it to fit over the tire nipple so the grip doesn't hit the tire or rim (this is normal). The thing is really light, at first glance it may seem cheap. The lightweight plastic body, rubber grip, air connector, circuit board and LCD display all add up to a light weight, but if you don't abuse it, it will last a long time. Have used it once so far. Maybe more reviews later, I have planned more use.
