I'll admit that with all the bad reviews I was a bit worried about this tool leaking. All I can say is that I either got a good one or Motion Pro fixed the problem. The head on the shaft rotates freely and without leakage. Taking 2 stars off for "value for money" because it's expensive for what it is, but it makes it easier to deflate the motorcycle tires as the brake discs and pulleys make the rear tire harder to work with.
