Review on BACOENG Mini Split/HVAC/AUTO AC Repair Tool Kit with Tool Bag - Includes Powerful 3.6CFM Vacuum Pump and 800PSI Manifold Gauge Kit by David Robinson

Well I've noticed metal shavings in the collector which certainly wouldn't be good if they got into the AC system I'm charging. But for the price I find it unbeatable. I was just practicing taking a good look at your lower end and even expensive instruments these days. I've disassembled the distributor, cleaned it and used it a few times and it seems to be working fine.
