This is a great set! Has all the options you need in a manifold set. I compared the Mastercool but it reflected the price difference in quality. I looked at the more expensive fieldpiece but Testo was a little less. Took me three times to get a good one. The first one I ordered was an opened box item. Supposed to be complete, just a damaged box. It showed up without the hoses. The second one I ordered showed up in a box in a box with an old shipping label cut off the inside box. Made me think it was previously returned as well. Didn’t keep it. The third one I ordered appears to be the real deal.

The Testo 552i handles a vac of about 23 microns ok, but it is horrible for a decay test. When testing the unit with a brand new Appion core removal tool and directly hooked with the pump. The unit LEAKS bad.I DO NOT RECOMMEND THIS UNIT.

Can’t wait to use mine on the equipment.

These are 100% worth the money I’ve been using analog gauges for 6 years and finally decided to make the switch and these are a must have a total game changer if u wanna take ur hvac career and service to the next level these are a serious must have
