From rookie to pro in one tool upgrade
This is a game changer for HVAC work. No more refrigerant losses when taking readings. No more trying to read the gage to get it roughly accurate. No more struggles to get reliable temp reading. Ability to readout values from a distance on an easy to read app. This pays for itself in time saved, refrigerant losses, accuracy and "Tool Pride"! Costs a lot but well worth it. My only negative is the apps available limit their features unless you subscribe to a service and I hate subscription scams. Still the basic free app that comes with is adequate for a hobbyist or part time HVAC guy and your company will buy the subscription if you work for a legit company.

A great tool
It connects directly to the air conditioning system's service port, minimizing the need for connecting hoses and excessive fittings, thereby reducing refrigerant leakage to a minimum. Furthermore, real-time measurement data can be read directly via a mobile app. This is an incredibly professional and efficient tool for HVAC contractors—it's fantastic!

Good product
Excellent product. I have the Testo gauges with hoses, and I recently bought these gauges. I recommend them for making quick diagnoses without using hoses or losing any Freon. They are really accurate, i use them with MQ hvac app

Actually
My husband say they work exactly as described.

Solid performance
They work good. The downsides are having to sign into an app periodically and the clamps have to make clean contact on both sides of the clamp (continuity between sensor jaws) which can be a pain in the neck sometimes; all other wired clamps I've used didn't require this. Trust me, it can be inconvenient at times, otherwise, I appreciate the quality.

Convenience worth the price
Works great, its very handy to be able to monitor pressures and temps while working in an attic space or while completing other tasks. Compactness of bag helps when visiting customers home, it reduces the size of my tool kit and I done have to worry about the probes getting damaged when working in attic spaces. Love that I don't have to purge hoses now and that I can monitor just one side as needed

Saves time and space
Very cool and impressed with the minimalism and technology here. You're able to check your pressures without needing to purge air in the hoses (at least for your diagnostic stage). Even hooking up hoses can be done easily with a T-valve. I was impressed with how far I was from the unit I was still able to read the gauges on my phone. Very impressed so far. Will update the review if anything changes in the long run.
