  • Works great
Style: Basic Kit Pattern Name: Digital Manifold
The gauges have been working great. Temperature clamps are great and no problems yet. Plan on using the Bluetooth feature this year. Using Bluetooth temperature clamps.

  • They are okay
Style: Vacuum Kit Pattern Name: Digital Manifold
This is the same critique I have with the smart probes, these gauges always seem to read 3 to 6 psi off. It must be a new transducer that tester was using because this never happened with my old gauge manifold. The 3 to 6 psi may not be a big deal for guys working with 410a but when you’re working 134a 3 to 6° 10 throw off your superheat or sub cooling reading substantially. They can be zeroed out when you first turn on the manifold but um, I last said I never had to do that and then wanted zeroed out. I have a hard time trusting it. ... show more

  • Nice gauges
Style: Temperature Kit Pattern Name: Digital Manifold
So far these are nice! I like how small and compact they are, easy to use, and I also like how everything connects with each other thru Bluetooth. So far they are accurate and have no issues.

  • Love these gauges, best purchase I’ve made in a long time
Style: Vacum Kit with 3 Hoses Pattern Name: Digital Manifold
My only complaint is that the suction smart probe doesn’t want to connect. I know there’s videos and posts online about other people having the same problem so it would be nice if they fixed that issue. Even with that issue, I’d still give 5 stars. Other than that, these are top notch! Absolutely comparable to, or in my opinion better than, the field piece gauges that are more expensive. I have the app on my phone so I can move around and do what I need to do while checking pressures thru Bluetooth with a click. If you charge using superheat, I HIGHLY recommend this set up plus the thermohygrometer from testo as well. Also Bluetooth, so you can see your wet bulb reading on the indoor from outside, saves me tons of time going in and out, up and down stairs. These gauges will do all of the calculations for you and makes the job so much easier. The Vacuum sensor not working doesn’t bother me one bit honestly, but it may be an issue for someone else so make sure you register your warranty and contact them, I haven’t yet, but I’ve heard they’re easy to deal with. ... show more

  • Pretty cool but expensive

This is pretty cool maybe a little faster to use than gauges but I still like regular gauges.
