Stays put and does the job
Style: Contempo
I hate clutter. That includes my sink area. This holds my oxo scrubber and a sponge with ease. It also lets everything drain nice so there is no issue with slime or smell that other caddies have. Looks nice and amazingly the suction cups work. So far the finish is holding up and for what it is, it does its job. Looks nice.

I liked the style and shape. However, I cannot get the suction cups to stick.

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.

Pretty good, take your time and install it well
Size: side table leg
Materials are pretty solid, but once assembled it’s not as sturdy as you would think it should be since the material itself was solid, i say give them a chance, everything out there that’s similar is way over priced

Heavy duty legs for table.
Size: side table leg
Perfect legs for a table I am having made. I have an cottonwood slice. It's heavy and needed something substantial.
These are perfect.
