Very high quality sensor. I was excited when he came and it was night time so I held him to the lamp and went outside and checked my tires. The glow-in-the-dark gauge was easy to read, and the end cartridge held pressure without hissing, and the release valve worked very well, relieving pressure so you could read the dial when it fell off. I was fed up with the random readings from my digital mucus sensor, which this sensor said was 5 pounds higher. I had my tires checked at my dad's shop and his gauge matched mine so I felt good. The ride was better as the tires were inflated and I have 3 cars and 3 bikes and tire pressure has always been very important to me. I love knowing my tires are inflated with property and now I can do it with confidence! I could get one that connects to my air compressor for maximum convenience, but this one is great and portable for now. Great price, I don't need any extra gimmicks that fail so I bought the base model. The digital gauge they sell is more accurate, but I wanted to move away from digital for this purchase. I decided to do a long search and when I came across the Longacre I knew I had found a good product based on feedback from all the riders. America only makes idiots and celebrities, so I don't blame her for being a foreigner. Every vehicle and all of my clothes, shoes, phones and computers that I leave this review on are overseas so who cares where they are made.
