The new McKee's 37 rinseless sponge and drying towel look really cool but I don't understand the logic of making one side black. Personally, I prefer lighter colors so you can see if it's clean or not. I must be in a minority since the DIY legacy sponge has a black side and they didn't change the color when they recently revised it.
I feel the sameway.
Lake Country has just recently release an updated blue sponge. Looks interesting since they actually work/manufacter with the foam.
I have the Big Gold Sponge its holding up fine after about 4 years.
