Review on 📱 Testo 557s Kit: App Operated Digital Manifold with Bluetooth for HVAC Systems by Jason Morrison

I've been using the gauges for a week now and so far so good. The reason for the 4 stars is that I bought a Testo that had hoses in it. completely OTHER! On the first day all 3 seals flew out of the hoses and I had to put my old hoses in. They are not junk from big brands. Buy a gauge and yellow jacket or hose set from JB separately and you've got a great setup. Why they included junk with a $650 distributor is beyond me. I wish I could get a refund
