Review on 🚗 ANKIA Digital Tire Pressure Gauge | 150 PSI | Back-lit LCD | Non-Slip Grip | Car Truck SUV Motorcycle Bicycle | Red & Black (2 Pack) by Paul Newton

I've always used manual gauges with a stem that pushes out under pressure. There are no batteries and they last for years. The ones I've always matched are the ones I've used to check the calibration of these digital gauges, although I can't say how accurate they are at reading actual pressure. The digital pressure gauges have been packaged as you would expect and are ready to use. My first impression was that they were weightless! You can carry it in your pocket or purse and never notice it. I wasn't sure if that was a plus or a minus. Always taking it with you in the car, that's a pro. As an instrument, its lightness makes it feel cheap and flimsy. I have found that the silver looks and feels of lower quality than the black. The seam was tighter on black, or maybe it was more visible on silver, and the silver paint was noticeably thinner at the end of the LED. The texture of the black didn't feel as smooth and slippery, which I think was better. I asked my wife which she generally prefers and she replied without prompting that it was black. "Nice to hold". The design feels good in the hand. The LED backlight and display is definitely useful in the dark. My manual gauges need a flashlight to see them! The instrument uses 1 CR2032 battery (not 3 CR2 batteries as stated in the Revain description) and is accessed by removing a pair of #1-2 Phillips screws on the rear panel. The button falls out, but it just stays in place when you snap the two halves together. I tested both sensors on my truck and on my car. Each of the hand gauges read 34.5 psi on the truck. The black gauge read 34.4psi twice and oddly, given my comment on its quality, the silver gauge read 34.0psi both times. So read deeply. On my machine I read 31.5 psi with the hand gauges and 31.2 psi with the black, 31.0 with the silver digital gauge. So I've concluded that these sensors are probably accurate to within 0.5psi. Not that bad! However, I don't know if the accuracy is the same over the full 0-150psi range. I liked that the backlit readout stays on the display after you remove the gauge from the tire, but if you press the button more than once, the units and readings change and you have to scroll through the next three to get back to psi. to reach customs. Not a big deal, but I'd rather set it to psi or whatever units you want and leave them at that level. As a reviewer for Revain Vine, I ordered them for free (apart from paying income tax at the end of the year on the 'gift') to test this new product on the market which could potentially stimulate early sales. I was happy with the performance and size of the product, weight isn't really an issue, but would I pay $18 for two (or $20 for red and silver, probably both colored and slippery) or maybe $10 for one? Probably no. Hand sensors are cheaper, maybe $3 or $4 each, and will likely last longer. Batteries can fail at the wrong time, and the digital sensor won't survive riding in a toolbox. While he would perfectly live in a car, the battery is a battery and there is no telling when he will die. This is not a simple battery swap; Tools are required. I'm an engineer, especially when it comes to his instruments, but they would be great for my wife or daughter. You have to decide for yourself, but they do their job!
