Review on Elitech DMG-1 AC Manifold Gauge Set 2 Way for R134A, R410A, R22 Refrigerants - Includes Hoses, Coupler Adapters, and Carrying Case by Reggie Hobbs

My BIL had a SNAP-ON set that was on its last legs. He was helping fix my air conditioning on our minivan and wasn't sure how accurate his 15 year old kit was. The third time we used this set we saw what was changing in real time, even in decimals, which really helped us to see that the expansion valves were doing their job as intended and confirmed that my system was working. My ONLY issue is that the digital screens turn off after a set time to save battery. Thankfully, accuracy and tracking are maintained when you hit the power button. It might be a setting we can disable, but it's not really something to deduct a star for.
