We really liked these sponges they worked really well. I gave this 3 stars ONLY because it states ONE sponge is supposed to last a month. It does NOT last a month in a family of 4 that does dishes 2-3 times a day! We went through the whole pack in about 3-4 weeks. To me for $15 for a pack of sponges thats alot of money. I can spend $2 and get 12 sponges and they would last 2 whole months or longer. That is my reasoning behind the three star review. They are a good quality sponge, but just dont last as long as advertised, and in my opinion over priced. Im sorry!
