I've always been a big fan of liquid soaps, especially when it comes to hand soap. That's largely because I can't stand the soggy mess that soaps become after sitting in a wet soap dish or on the corner of the sink. As if the mess it made wasn't bad enough, sometimes the soaps get so soggy that your hand sinks right through them when go pick them up.
But the Idea Works Waterfall Soap Saver solves that problem by letting the water drain out right into your sink, keeping your soap usable much longer and your soap dish less crusted with soap goo.
