The OXO is OK, but it's hard to flatten because of the stiff round rubber "scrubber" end. The WHEEL and BRAKE DUST BRUSH sold at Wal-Mart can be flattened VERY easily. The OXO brush couldn't get by the front rotors of the new Accords with 16" wheels very well. The metal bristle cores don't look like they will contact the wheel...use common sense. :usa
Edit: The OXO is good quality. The Black Magic brush is "thin", but lesser quality and I prefer the Dust Brush over it. Each has it's usefullness depending on the wheel.
