Bests & Worsts Reviews from Amazon

I have NO idea why this product would ever have less than a 5 star review. It is a great brush set, I used all 3 in an effort to get some mildew stains off the grout in my shower. NOTHING worked, but a bit of soft scrub (bleach) and these brushes worked like a charm! I then used the larger brush on the floor of the shower, and to remove some soap scum from the glass shower doors. WOW! Where has this been all my life?! Excellent product, works like it should in conjunction with your power drill.
