This sponge holder is a simple upgrade that makes a big difference in keeping the sink area clean and organized. The suction cup holds firmly to the side of the sink, so it doesn’t slide around or fall off like cheaper options. It easily fits both a sponge and a steel scrubber, keeping them elevated and allowing them to dry quickly, which helps prevent odors and bacteria buildup. The open wire design is especially useful because it allows water to drain instead of pooling at the bottom. Installation is quick and requires no tools—just press it onto a clean surface and you’re good to go. It also keeps the countertop clutter-free, which is a nice bonus. Overall, it’s durable, functional, and does exactly what it’s supposed to do. Great value for anyone looking to keep their kitchen sink area tidy and hygienic.

Nice if the suction cups wouldn't have been deformed

Size: 7.125 x 2.875, Color: Brushed Metal

Update: The one I received had two suction cups deformed and wouldn't stick to the side of the sink. Realized this after placing it. Unreturnable. Perfect size. A little wider than the rest. Replacing my last one that didn't rust for years. It was fine except the hard water made the suction cups not stick otherwise it was lasting for years.

Needs modification to work correctly.

Size: 7.125 x 2.875, Color: Brushed Metal, Size: 7.125 x 2.875, Color: Brushed Metal

It is okay, but the brushes fall through the holes' making them hard to retrieve. The only way to get them out of the holder is to pull up on the bristles or push the handle from the bottom. Both don't work well. My solution is simple, just install a "stop" below the holes. My solution is ugly but works. It took me about 15 minutes to modify.
