I bought this kit just to get my cart to the free shipping price, but it has actually been very useful. I use the valve stem core tool all the time for deflating both dirtbike and mountain bike tires. The air pressure gauge is also handy in its compact size.
I bought it as a back up and never opened it. Then I needed a patch for a bad tube on our race car. Opened up the kit and was amazed. Everything you could need to fix a tube. patches, glue, caps, stem tool. Kit is awesome. Will buy again it the future without question.
The kit is a great value for the price. It has 4 valve stems,4 metal valve caps,tire pressure guage,6-8 plugs,6-8 patches,glue tube, and plug insertion tools. It all comes in a small plastic divided case. For the price, buy a spare.
PS. buy a spare tube of rubber cement at the same from RMATV, the manufactor always supplies those micro glue tubes that are to small-!
