FAULTY ITEM • DO NOT BUY
Hmmmm.... I'm adding my review of zero stars to the others.  So, I think that makes 9 out of 13 reviews saying the same thing.  Don't buy.  The sponges come unglued to their plastic "socket" after about a day or two of light usage.  Wanted to have a few in stock as they are sometimes hard to find in stores these days. So, we didn't open for a week. When the first sponge came unglued (exactly as you described) after 2 days, we figured it was just a bad one. Then, same problem with the 2nd one. Now, it's too late to return. So, I threw away $15.00 I find more and more faulty items on Amazon when made in China.
