Great product
Color: Sand Nickel+Brush Holder
Very happy with this purchase. It is relatively compact so it doesn't take a lot of room in my sink, but big enough to hold sponges and wand. It also gives you the option to hang on wall or sink.

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!
