Looks nice
Color: Silver
It looks very nice. It has a streamlined design, not big and bulky. Quality is ok. I really like the look of it.

Compact
Color: Silver
Size fits well on back of sink. However, the bottom needs some kind of non slip traction as the unit slides a lot. Had to put something under it to keep from moving around.

This was a very disappointing purchase
Color: Silver
This kitchen soap dispenser with sponge holder looks really nice in the picture, but..... it is so......flimsy. It is so lite weight that it almost falls into the sink every time I try to dispense dish washing soap. I was really looking for something rather heavy in weight (because of the metal) but elegant looking. I guess this is just one of those items that you actually need to see and feel before purchasing. I kept it because I needed some kind of soap dispenser after another soap dispenser, of which I purchased from Amazon over a year ago, it was made of plastic, and it broke. It was heavy and really looked nice on my sink. I guess I am still looking for a good one.

Shows smudges on its stainless steel...
Color: Silver
Nice compact size sitting next to our SS sink. However, you'll spend more time cleaning the SS soap dispenser as it continually picks up fingerprints and smudges.
