The goods have been received, but they do not measure, the pressure gauge is faulty.
The tire pressure gauge has three very tiny screws that need to be removed in order to install the battery, but the screws are so small that I would need to go out and buy a special screwdriver that is small enough which would only have limited use; if I'm going to go out, I might as well go and buy a tire pressure gauge from Walmart for the same price or cheaper that doesn't need batteries.
