I love this sponge. Honestly. I won't wash dishes without it! It changes texture in hot and cold water, is completely scratch free, doesn't hold odors and lasts away longer than your average sponge. The patened flextexture that it's made out of is a semi closed structure that doesn't hold bacteria like other sponges. It's also dishwasher safe if you want to clean it that way. It's smiling face is not just for gazing into, it serves a purpose! It's eyes are for your fingers so you can get into those hard to reach cups and it's mouth was engineered specifically with your utensils in mind. It's so phenomenal that I wrote a persuasive speech on it for my speech class and everyone loved theirs! It's so cute and stress free it will even make your roommate/significant other WANT to do the dishes. Ditch your old sponge ASAP and discover for yourself why the Scrub Daddy is "America's Favorite Sponge." Seriously. You won't go back.
