Excellent Brush
This is the replacement brush I bought after the original Phillips brush that came with my new 4100 wore out, and there really wasn't any noticeable difference between them. Since these only cost a little over a dollar each, I change to a new brush on the first of every month, although I could certainly go longer.<br /><br />If you want a brush a lot like the original at a small fraction of the price, this is the one to get.
