After hearing all of the hype on TMF about these brushes, I purchased a few (Aloha charged me double - something about a "high roller surcharge") but whatever.

Unfortunately in this instance, my "no lies" policy has come back to bite me and by God, with reluctance, I concede that these brushes certainly worked better than the competition's. Sweeping sideways across the tiles, paid big dividends, grout...
