Great product except….
Color: White
Love the base of the holder and color! Plus the brush was a nice add-on. The soap dispenser was not as solidly made as rest of product. Had it for 3 weeks hoping dispenser will last. Would give all high praise if they beefed up the dispenser.

Good looking, sturdy & great value
Color: Gravel Black
This looks great on top of our Black Quartz sink (which is top mounted so fits well). Very sturdy and easy to clean. I recommend this.
