    • 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. ... show more

    • 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

    • Time and step saver
Easy to use and accurate. Blue tooth has a good range making it possible to read pressures from attics.

    • Great for ceilings, package units, or tight areas that are hard to get or leave hoses in.
Use these every single day at work. I love them and they work great. My only complaint is for the price I wish the app worked a little better. It loads and functions but after being open for 10-15 minutes I have to close it out and re-open it. That being said everything functions well and I’ve even purchased the compatible job link vacuum gauge and Bluetooth manometers since. ... show more

    • 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 ... show more
