  • Boom goea the dynamite!!! This is the real deal for all you HVAC guys!!!
Style: Test and Load Set
HVAC TESTOED DAD APPROVED!!! These are a beast. Much more durable than my last ones I love the plastic gaskets. It seals better than the rubber ones. Connects to mini-split adapters and to units easly. Very spot on accuracy and can be zeroed out. Easy to use and connecting the app and all the functions are awesome. I work HVAC industry and these work awesome!!! ... show more

  • 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

  • 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.

  • 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

  • For the money it’s hard to beat
Style: Test and Load Set
Great starter kit. Only reviews that I’ve seen that weren’t positive didn’t apply to my work. One was clamps are not temperature compensated clamps, but I’m not working in sub zero freezers. The others were the limited blue tooth range. The signal does get blocked by the walls of a house, but when you walk back to the condensing unit(s) they are automatically reacquired. ... show more

This item arrived and it was all thrown around in packaging, the new wrapping/seals were already removed and some of the items had dirt & black stuff all over them. Definitely used prior to sending. Returned item, as I bought new NOT used!
