  • Testo makes a great product!!!
Style: Test and Load Set
As a HVAC technician I have used analog, digital, and now wireless probes. The Testo Smart Probe Kit works absolutely fantastic. Works great with the testo app on iphone, pairing is a breeze. These probes have great range, feel durable in your hands and make diagnosing and testing much easier. My favorite part about the Testo probe set is that it cuts out taking refrigerant out of a system when you gauge up and risking contamination. Quality built product! ... show more

  • Great Tools to have
Style: Test and Load Set
When I first placed my order, my set came without 2 of the 605i’s. Got in contact with Amazon and they corrected the issue. In few days time, the probes reached my home. I tested the probes out on my home’s ac and it’s easy to use. Downloading the smart probe app is a breeze. Move over 557, the smart probes are my go to. Love them so much, I ended up getting the rest of the probes. I didn’t have a problem losing connectivity from different sites. I recommend them to everyone. ... show more

  • Testo VS Fieldpiece smart probes.
Style: Test and Load Set
I have been a big fan of Testo for over 10 years and that’s why I bought these.Very disappointed in the quality and design.Very cheaply made.They don’t have the features of the Fieldpiece meaning a led you can see in the sunlight,no warning if the temperature probes lose contact,better software,ect.ect.ect.The temperature clamp spring is to loose and won’t clamp on 1/4” or 3/8” on a vertical pipe without falling half off not to mention how slow the temperature clamps are compared to the Fieldpiece clamps.The fieldpiece is set is more expensive,but worth it.I have never been a fan of fieldpiece,but they have a home run with their smart probes.I still prefer Testo’s manifold over the fieldpiece manifold and hope they can make some improvements to their smart probes to be more competitive in the future.Until then I will continue to use the best product regardless of cost. ... show more

  • Not low loss fittings.
Style: Test and Load Set
Like the probes but I wish testo made their fittings low loss. Makes for some frozen fingers at times.

  • Oh Baby!
Style: Test and Load Set
Downloaded the app, switched on the devices and connected to lines. Data came right up in app. Display made sense and i found it useful. I would recommend to anyone in the industry. The LED on the on switch on each device is not that bright and its hard to see if it is on or off. Also they could have used quick disconnect fittings on the pressure sensors, considering the money they are charging. And on the Low side a Quick disconnect with a service Tee so we can sense and charge at the sane time. Came in nice case with retention straps and separate attached document bag. ... show more

  • Essential for keeping your dau short
Style: Test and Load Set
Best money spent, when the ac season hits and you have a long day of break downs this set up is very easy to hook up and go. The duct probes drop out the most but besides that they work like a dream.
