There have been MANY posts here and other RV forums about the Oxygenics Showerhead.
I just got a new Camping World e-mail Sale Flyer and they are showing a new style Oxygenics "Skincare" showerhead that has a different shape.
Here's the existing "BodySpa" showerhead that has been well reviewed:
And the new "SkinCare" showerhead:

Not only is it less money but it looks to have a built in shut off which the "BodySpa" lacked.
Lots of good reviews on Amazon but I didn't see any comments that referenced usage in an RV.
Anybody here tryed one yet???
Hmmm - It just occured to me that this is not a "handheld", BUT there isn't any reason you couldn't use it that way with a hose regardless.
