Beware of a sticky detail
I was looking for a way to organize my kitchen soap, sponges, and bottle brushes. This soap dispenser checked off all of my boxes with a nice stainless steel design making it a great addition to my kitchen counter. Question: after all of these positive aspects why only two stars? Answer: there is a sticker placed onto the dispenser that is so sticky that it is a formidable foe to remove (please review the attached photo). I liked this soap dispenser but the semi permanent sticker is the deal breaker to an otherwise nice product.
