It works fine on any bike or small inflatable boat but not great for car or truck tires. When I need air in my truck tires, it takes forever, and it's also very loud. Works better when the machine is running, slower when the machine is off. It has automatic settings that make it very easy, it turns itself off when done. It also has adapters that allow you to inflate both types of bike tire inner tubes. It does what it's supposed to do, hopefully it will last longer than others I've had.
