Query: not up to OXO standard

I purchased this sponge because I have had good luck with OXO Good Grips products in the past. While the button dispenses the soap well, the foam sponge is of poor quality and rips off from its base within one or two uses. I have purchased other brands of this same style sponge, and the OXO one is definitely not worth the money. Disappointing purchase.
