We had the problem that we took home with a stainless steel sink from the hardware store, which was prepared for installation on both sides, so that can always be installed independently of the orientation of the faucet at the back. The accompanying panel we found atrocious, which is why we decided to use the open-not USED- hole for soap dispenser. So we went after several intermediate steps, come to the donor offered here. The product is of high quality at the places where it matters and how it works as desired. The installation was painless, filling with soap from above with a bit of practice feasible. Also, the pump works as intended without problems. For us, the soap dispenser was a good choice, when we need to be sure the next few years no longer thinking about alternatives.
