It's functional. However, the fittings are aluminum, not brass. It doesn't change the fact that the tool works, I was just a little bummed when I picked up a really light weight fittings instead of a denser brass fitting. Also, the quick disconnect does not actuate particularly smoothly. Other than that, it has plenty of adapters and gives accurate readings. What more could you want?
