Review on π± Testo 557s Kit: App Operated Digital Manifold with Bluetooth for HVAC Systems by Nick Mitchell
Great pressure gauge! best air conditioning line repair tools
Good sensors, good performance, but the high-pressure hose leaked right out of the box. I would advise buying a kit without hoses and getting good yellow jacketed hoses.
Pros
- Hands-free operation
Cons
- I vaguely remember
