I needed a good gauge and as it was a two pack I decided to give it a try. When I picked up the device for the first time, I immediately noticed that it has good ergonomics. You may not think this is important, but if you're trying to check tire pressure at an odd angle or in a tight spot, it's very important. Especially if you accidentally try to keep your air out. Case in point: I researched the highest rated tires in consumer reports. It was Accutir. I have owned this meter for several years. It is very inconvenient and awkward to use compared to Geartronics. I also wanted to test their accuracy against Accutire. You read the same readings on multiple tires! I am impressed. In addition, the screen is easier to read on these devices, and the illuminated tip is a handy feature in low-light conditions.
