The product is excellent! The ergonomics of the handle make it great. If you've ever used a similar product, you know it can be difficult to insert a connector. I live on a gravel road that appears to be a mixture of gravel, arrowheads, and drywall screws. I fix 7 to 8 a year between myself and my family. I bought this kit for every car and a portable air pump. No more calls for AAA.
