Review on 🔧 Powerful AUTOGEN Portable 4CFM 1/3HP Air Vacuum Pump: Ideal for HVAC R134a R12 R22 R502 A/C Refrigeration | Complete Kit with Manifold Gauge Set, Leak Detector & Carrying Tote (Without Oil) by Tay Tran

The packaging was good and arrived as expected. Disappointment rating was 4/5 as the faucet is not what it should be so I had to buy another locally. Both gauges worked, the vacuum pump was enough to get the job done. The plumbing was fine, but I needed adapters to connect self-closing jars. I originally wanted to return it (I don't like giving back) so I managed. I definitely think they should throw out what can knock and put it in a better one. It would make their ratings a little bit better. One of those "you get what you pay for" clauses. The bottom line - he did what I needed to do.
