Review on 🚗 Complete Automotive Hand Held Vacuum Pump Tester Set with Vacuum Gauge and Brake Bleeder Kit – Includes Adapters and Convenient Case by James Lapa

I bought this to test vacuum components. Before you can test vacuum components, you need a tester that can withstand vacuum! Straight out of the box, no hoses connected - just blocked the connector with my finger. The device pumps into a vacuum. then watch the scale slowly return to zero. I checked everything for leaks. still flows like a sieve. grabbed the phone from my bank. Just in case my finger was leaking. nope! Still won't hold vacuum. Sent back for exchange. The new one was worse than the first! Sorry if I could give this product less than one star I would!
