I like that the pressure gauge in the east seems solid but the problem with the tip, it has a ball that moves from one valve to the other but it does it doesn't work well at all. I disassembled and cleaned it, but that cheap plastic ball makes it difficult to change the valve that is leaking air, even $5 cargo ships in port don't have that problem. My friend wanted one so I bought him a clone that works better and is cheaper. Update: The gauge is outside of the 10psi gauge, even my Harbor Freight was within 2psi and has been leaking out of the cartridge shaft where it connects to the hose since the day I understand it. I wish I could buy a copy of this my friend has which is cheaper and clearly better.
