I gave these to the men in the family as a gift. I decided to try it myself- all the girls are going to be getting them now. This product is not flimsy at all and you feel clean after using it. I love this "men" tool!
Maybe I'm misreading the instructions, but it seems to say that you use the "scrunchy" side to develop the lather and use to scrub side to, well scrub. I'm not too keen on the 4-6 week time frame as It seems like adding to useless landfill. Very nice with the deep clean body wash!
