AmazonBasics Programmable Digital Tire GaugeThis tire gauge looks exactly like the newer Accu-Tire programmable gauge. The first thing you should understand is that the programmable aspect is just a reminder. Whether you actually program the gauge is not significant, I found that it doesn't really serve a purpose when I use the gauge on 4 different cars and a motorcycle which all have different tire pressures. For instance, one car has 32 psi front/rear while the motorcycle is supposed to be filled to 32.9 psi in the front and 36.9 psi in the rear. This Amazon tire gauge only reads tire pressure in increments of 0.5 psi, just like other digital tire gauges.The Amazon gauge is rather large, heavy, and bulky. There are rubberized coatings on some parts of the gauge to provide a better grip. It automatically reads the tire pressure when you hook it up to a Schrader valve on a tire. It quickly resets, but not so quickly that you don't have time to register the reading. The SET button allows you to manually reset it for the next reading.I compared the readings on this gauge with myCampbell Hausfeld AU110000AV 99 PSI Key Chain Digital Tire Gauge, and they matched exactly. I compared the readings to that of the on-board TPMS on one of my Chevy cars and it was within 1 psi.My biggest complaint with the Amazon gauge is the "release valve". I purchased this thinking there was an actual release button so I could release air and check the readings in real-time. Unfortunately, it is just a machined nub that pushes in the Schrader valve on your tires. The seal on the gauge isn't that great and requires careful alignment to ensure no leaks.That said, the release valve nub came in handy. I have a set of tires on a car that have Schrader valves with really short stems that don't seem to accept the ends of the caps or even my finger nails. The nub on this Amazon gauge was able to release the air without any problems.The Amazon gauge was also perfectly compatible with all of my vehicles, and the swivel top allows you to use it in odd/hard to reach locations. The backlit LCD display is also easy to read as long as you keep the display at a flat angle to your face. Apparently the polarization is very strong because if I tilted it a few degrees away from my face in any direction, the text disappears.The Amazon gauge comes with a semi-rigid zippered case that makes it handy to keep in your glove box or in a purse/bag, or a tool kit. The instruction manual states that it uses a pair of CR2032 lithium coin-cell batteries, which are more resilient against temperature extremes and have a decent storage life (3-5 years).Overall: 4/5 stars, rather pricey but seems to be very ruggedized. Swivel top makes it versatile enough to reach all odd-ball valve locations. I honestly could live with using my cheap Campbell-Hausfeld keychain gauge even though it isn't as fancy as this Amazon gauge. Also, it looks like this gauge is just a rebranded Accu-Tire gauge.
