So far so good!
Color: Silver+Brush Holder
It’s only been about a week since I applied it, seems sturdy enough, and the adhesive was sticky enough that it seems secure. I use very hot water to wash dishes due to illnesses and it’s held up well to the heat of the kitchen thus far using just adhesive. Good buy!

Color: Black+Smiley Face
The suction cups don’t hold and my smiley sponge isn’t snug on the post so it sometimes falls off.
