Definitely Gets Dirty and Waterlogged
I've had this for a year and I will say it definitely gets really dirty.  Yes, it cleans well and is easy to use but soap scum sticks to it like crazy.  The power button definitely gets waterlogged.  Mine stopped working/basically started turning on by itself!  I had to take the batteries out of it completely.  Wish I could get a replacement one.
