Review on Efficient Brake Fluid Bleeder Bottle with Non-Return Check Valve - FIRSTINFO 33 Oz (1 Liter) Capacity + Hook Fixed by Marco Maurer

Universal adapter doesn't fit exactly. It's at the bleed screw... but the brake fluid will come out when you start bleeding. Not much liquid comes out, but enough to understand that it's not securely fastened there. I double checked that the adapter was indeed loose on all my wheels. Keep flowing. So I quickly went through the whole process and sprayed all the leaks with brake cleaner. Single ended hose is good. It keeps the fluid inside and doesn't move unless you pump brake fluid and/or air into the hose yourself. The hose is nice and clear and you can see the brake fluid moving through it. I don't know if the hose will stay clean over time, but I hope so. The bottle is made of hard plastic, which is great!
