The nozzle provided a good seal to minimize any air loss and I verified that multiple gauges produced identical results, giving me confidence this works well

Easy to use, seats easily over valve with little air loss, easy to read, intuitive.

Sometimes doesn't go on to gauge without some air loss, but it could just be that I am a new user.

Arrived quickly in one day and all works as it should I also purchased tire inflater attachment with digital pressure readout screen for my air compressor and this to works perfectly.

These gauges work as they should

They work as they should so far.
