door to door scammers.i hate them.they come to the door and tell your wife they are hot and try to sell them colored water in a bottle ,what they dont show is the abrasive pad or cloth they hide from you that is actualy cleaning the surface you havent touched in years then it magicaly gets cleaned and you purchase there bottle of colored water for 36 plus dollars ,when you are on to them and you cut them off during there spiel if you can get a word in and tell them no thanks your not interested - they immediatly become rude and agressive and all of a sudden not so funny anymore .id like to see there review of the product after they purchased it.
