OMG! Everyone should have it! One when my tires have a slow leak. Unfortunately I share a car with my son who almost got a flat tire. Once I drove a car without checking a tire. Luckily it wasn't far. I felt a difference maneuvering the car so I checked the tire as soon as I parked. She was half emptied! I just bought a compressor, so this is my first time using it. Directions were simple and easy. The meter is accurate and my tire filled up in just a few minutes! I bought a new tire but it makes me feel good knowing I have a compressor in case I need it for other purposes or to help someone else!
