Long story short !! good and convenient device for easy DIY-venting or newly-filling the brake system !! Easy to connect and good description in the operating instructions! Only one should be careful, that's not too high, the set pressure on the container! 1 bar ranges from more than one !! From me there is a star deduction, because the screw on the cover, which is screwed onto the reservoir, was slightly leaking and me went wrong a little brake fluid! But it was not so bad! Otherwise, great value for money
