Massaging Bath Pillow

I need this right now because my neck is absolutely killing me. It's a waterproof massaging bath pillow from Hammacher Schlemmer and it attaches to the smooth surface of your tub, providing a "gentle vibrating massage". The sounds absolutely heavenly right now. I prefer showers over baths but this is could change all that. Or maybe I'll just put it on my bed and lay down there...

Oh, and it also plays "soothing natural sounds", but I'm not after that; I just want the massage part.
