Review on DASBET Hand Held Vacuum Pump Tester Set: Ultimate Automotive Vacuum Gauge and Brake Bleeder Kit by Aaron Schultz

Low suction, max 15-20. Poor quality, didn't expect much. You get what you pay for. Pressure gauge is leaking. Had to use tape and tighten to seal properly. I didn't want to spend time replacing to get the same result. read reviews. 5-star ratings from customers who are tolerant or unsure of how the product is supposed to work. The adapters do not seal the bleed screws. Use hose only. The supplied hoses are short. The attached document and the package contents listing indicate that it comes with longer tubing than what you will receive. Clean your hoses and protective reservoir or the brake fluid will eventually eat through the seal on the can and further break the seal.
