Stainless steel soap dish with suction cup

No more soap scum in the shower, bathtub or sink! 
 
You stick the serrated part in the soap, the other part has a suction cup that you can hang everywhere and the whole thing is magnetized so that when you're done soaping up, you can put the soap on the part with the suction cup. Isn't that too convenient? 
 
PS: The soap is not included in the purchase, thank you for your understanding.
