I really wanted to try this product after I watched the Shark Tank episode. I was not disappointed in the slightest. This is hands down the best sponge I have ever used in my life-- and I have washed A LOT of dishes! The sponge can be used soft or hard. To make it softer for surfaces you don't want to scratch, such as a griddle or nice pan, just wet the sponge a little more before use. This sponge scrubs off the toughest of stains. I used to get so frustrated with stains on pots and pains, but not with the scrub daddy. I usually purchase this at my local Kroger. I haven't found it at any Walmart store, but I know you can purchase them online at Walmart. At Kroger it usually runs around $4.00. It is worth every penny! I use it for a couple of months and then switch out with a new one for hygiene purposes. I have bought multiple of these sponges and will never go back to the ordinary dish sponge again! The no scratch claim is 100%. None of my tough surfaces, or things that worn you to be careful when washing the surface (my griddle) have never been scratched or anything else. Great product, a must have in the home!
