Review on YSTOOL Brake and Clutch Fluid Pneumatic Vacuum Bleeder Tool Kit: Efficient Brake Oil Change Set with Extractor and Refill Bottle, Master Cylinder Adapters, Air Quick Plugs for Automotive & Motorcycle Use by Demetrius Holt

Not suitable for shop use. Suitable for home use. First, it's mushy. It breaks easily, cheap plastic cracked when a 14mm head first fell on it (head can't weigh more than a few grams). I glued it on with two part epoxy because the vacuum was $20. Whatever.Two - Extremely slow sucking. Slower than any of my colleagues. Three - Brake fluid starts spraying out of the air vent when the reservoir is half full. I wasn't expecting this when I first used it and halfway through bleeding the brakes I sprayed the car and a passerby when the tank was halfway down. If this one breaks, I won't buy one anymore. Better to spend $100 for something that works and won't break if you're overbreathing somewhere nearby. Also, brake fluid eats away at the paint and I was unhappy with the brake fluid paint removal on a $50,000 2020 car. Luckily I was quick enough and the fluid didn't eat through the paint. Not a great product. Tolerable quality even if you only use it once every 3 years or 30,000 miles (recommended brake bleed interval).
