Sturdy tools, built and working as described. The only reason I gave it a 4 rating was that the adapter tube was too thick to fit in my aluminum rim groove, so I couldn't get the tube close enough to the rim for the valve to push through. What I had to do was make the extension out of slightly thinner plastic so I was flush with the rim. It is very important that you are flush with the rim when pushing the valve through the reducer tube. With my short extension at the end, I was able to fit it in just right. Never seen before --- pretty slick!
