Since I'm in the market for a new micron gauge, I figured I would try the digital manifold with micron gauge built in.
I've read the bugs in the Testo 550 model, just wondering if they were rectified with the 557 model?
I've seen these on sale for only $100 more than the SMAN3. I've regetted most Fieldpiece product purchases, so the $100 savings isn't going to make me purchase something I don't have faith in. I can't afford the Yellow Jacket set for nearly $800, and the Digi-cools don't have a micron gauge.
