They are inaccurate, and have lots of issues.

Yes I have it set to r 22, yes I blow it each and every time I change refrigerant, which was only once.
Its been the worst tool I ever bought, and I am not impressed with testo's customer service. I don't think I am ever going to buy testo anything ever again.

I tried it today, hope the gauges are easier to use because I couldn't get it to read pressure. I tried while pressing the tire button and not pressing the button, not sure what happen.

While I am a DC fan (never tried a Testo digital gauge set)... I do own some other Testo products: 327 combustion analyzer, 410, 510, 610, and a few others... they are all designed with thought and all work well.

I have a 557 And sent it in. My bad. I did not fully rely on the manual. But the kind folks thru Mr. John Bickers gave me a free calibration check and firware up date.
