I love these things. They perform well they are accurate and easy to use, and awesome price compared to buying at a supplier near me.

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 hoses that come with this have garbage O-rings. I’ve been doing hvac for over 10 years and never burned my hands so much than when using these gauges. The gauge itself is great, but is definitely recommend different hoses.

Muy prácticas

This gauges are totally crap , stop working right after the return window closed , the screen went blank . Called testo they want me to send the gauges to them and their technician will check the gauges and will charge me for the service. Total nonsense. DONT WASTE YOUR MONEY

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

Su tamaño es exelente para el uso de transportarlo no es bromoso como otros que he tenido
