So I've watched about 25 to 40 videos from Testo in the last 2 hours looking to get new gauge set but it looks like all these 557S have bad port alignments if you look at the four port connection you'll see that the dummy port is either straight ahead on some and then slightly off on the others or one of the other so that you can't connect the hose quality control needs to be improved for these prices
knock on plastic nice set of gauges. good signal from app while working inside. BRAVO TESTO
Thinking about picking these up soon to replace my 549.

The dummy port are like the revolver Jb s. They spin around .
Can I use second generation pressure probes with the 557s?
Just got em!! 👌
Just ordered mine.
Great product, but please stop using those cheap white hard plastic o rings in your instruments.
bad product dummy ports are placed so no hose can be attached look at video behind handle
