This is a great item that can be used for a number of automotive and household applications. I mainly used it to bleed the brakes, and I was able to extract all the dirty brake fluid. The item performs better than its plastic counterpart sold in the auto parts stores. It also comes in its own box with numerous adapters, hoses, and instructions manual. When bleeding the brakes, the item builds the vacuum and is able to extract the fluid. However, air bubbles will also enter the line if the tubing is not sealed at the bleeder valve. This is not due to item malfunction or defect. The pump works as intended, and its usage is beneficial when siphoning fluids and doing vacuum leak tests. It looks durable and appears to be made for professional use.
