Strong scrubber but black sides wear off onto your bathtub if not careful
The brush is strong and it scrubs your bath tub or shower floor with a lot of force.  Must have a strong arm and wrist to hold the drill steady while the brush is spinning around.  The one thing i don't like is the side/rim is black and some of the black plastic rubs off onto the white bath tub while using it if you are not careful... especially near the side of the bath tub's interior.  So best to use this on a flat surface only.
