The only thing I regret about buying this tire gauge is that I didn't get it sooner. I watched it for about 6 months and finally bought it. It was a little scary spending that much without seeing it. I have too many of these things leaking or blocking the gauge. This thing is sturdy and very accurate. I checked with a good quality standard sensor and it is accurate. I love how you can add only what you need and get accurate printing. The fastest, easiest and most accurate instrument I have ever used. The actual display is quite large and very easy to read. The case is covered with rubber, which makes it comfortable to handle. The end is securely attached to the tire with no leaks. I even use it on my quads that use 3.5 and 4.5 pounds of air and it dials it up just as easily. The best I've ever used!
