This kit is easy to use and very well made. Everything has its place and stands out with the red lid in the dark trunk. I will never leave the house without him again. Not only has this saved me from having to buy new tires for my lawn mower, but it also saved me having to tow it to a tire shop for my car. I will buy one for every car we have! Easy to use and durable tools. It has everything for an easy repair. Valve depressurization tool, extra valve caps, case opener, lube, resin strips, rubber bit for smoothing holes and resin strip applicator. Also a pressure sensor.
