I got the Scrub Daddy in my stocking for Christmas from mom. (Yes mom still gives all the kids stockings and we love it).
I started using this cute little guy few days later and I LOVE it!
You can use it to clean almost anything. It doesn't scratch so it's a great for pots and pans. The nifty thing is when it's dry or used in cold water it's kind of hard so it's almost like an abrasive sponge (but non-scratch). When you wet it with warm water it becomes soft and spongy like.
