Takes alot of learning the app but it works Great! Very accurate readings, durability, and the battery power is outstanding. Worth the money. Try rigging the pressure sensors to you manifold using 1/4" T fittings as some Service fitting are hard to access if you try to connect your Testo directly on the Condenser. Its a Great buy! I've had mine for over 2 years and still working perfectly.

Edit/update: I thought the app was not updated/compatible with the newest version of Android 10, apparently the app doesn't connect to the probes unless you have your location services turned on. After the Testo Smart Tools stopped working, I bought the fieldpiece equivalent (far better imho), and... they do not require your gps to be on. So Testo, why do you want my location? If the fieldpiece app/probes connect without the GPS being on, surely this means it is not an android limitation...

After not being able to use the probes for a week due to connectivity issues. I did some research and found that after the new android update, you have to go into the app settings, enable location permissions and turn on your location in order for them to connect. Pretty annoying, but really enjoy using them. Works for both my Pixel 3a XL and Samsung A70 again.
