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.

Strong legs, somewhat industrial but trendy also
Size: side table leg
Good legs, some what utilitarian or industrial, they are strong as they are made out of pipe, and assembly is fairly easy once you get the idea of how it goes together. They are roughly 1.5 feet across maybe a bit less adjustable height on each leg, if you have wood floors you may want to put a pad under each leg as they are full metal pipes. Pretty interesting idea and does not cost much.
