Review on 💪 Powerful and Reliable: MASTERCOOL 6 CFM Single Stage Vacuum Pump (Model 90066-B) by Ruben Saunders

Good lightweight pump for the money. It pumps up the system pretty quickly. The only thing I don't like is that this pump is made of cheap materials. You can't throw it around like more durable pumps. The metal cover over the motor fan is very thin and easily damaged as mine did twice. It should be kept in the box between uses or during transport. I like the fact that it's lightweight, bleeds the system quickly, and doesn't cost much. Time will tell if this was the real deal. It has worked well 20 times I've used it.
