Review on Enhance Automotive Performance with 8MILELAKE 21pcs Handheld Vacuum Pump Set Tester and Brake Bleeder Test Kit by Masud Taylor

This seems to be a good quality. Good value for money. If you're using this to bleed the brakes, be sure to twist the cuff at the end to create a vacuum rather than forcing air. I have no idea why they set it to airflow, but it is. Imagine my joy and excitement when I think I'm creating a vacuum at the exhaust valve and then I hear air bubbles coming out of the brake fluid reservoir. Luckily it wasn't pushing air through the entire system and I was able to fix that.
