Review on 📱 Testo 550s Kit: App-Operated Digital Manifold with Bluetooth, including 2x testo 115i Pipe Clamp Thermometers, 1x testo 552i Micron Gauge, and a Set of 3 Hoses for HVAC Systems - Black by Keith Alvord

Not very good quality.

Don't get me wrong I like the simplicity of these gauges so I bought them but the quality is not to my liking. First, the clamp connector broke within the first month. The location of the clamp connector on the pressure gauges is unfortunate. When the clamps worked, I had to press hard to get the temperature reading from the clamps. The screen is very sensitive, one swipe and you have a scratch on the screen. When I turn off the screen, it turns off, but then I return to the screen with the words "press and hold to turn off". Because of this, I have insane battery drain. The only way I can reset the settings is to remove the batteries when I call customer service. I tried calling Testo customer service but they want me to send gauges so they can diagnose them in 1-2 weeks without gauges unless you buy a new set. As a service technician I can't live without pressure gauges and after spending $400 I don't have the budget to buy others but I think I will too. I've only had these sensors for two months. I go with the sm480v field part, make no mistake.

Pros
  • Slim design
Cons
  • Long delivery time
