Yup. I know some people love them, but I've got two, both purchased within the last 3-4 years. When you flat and are carrying your blackburn you have two choices: (1) Suffer terribly and try and pump hard and strong for a long time to get to 80-85 psi, or (2) pump it up to 50 or 60 psi and limp home.
