Negative Positive
Title: disappointing, particularly for the price...
Review: I decided to pay for the more expensive unit of all availiable, in hopes that it would be a better quality. I use filtered water, and after just a few weeks of use, have noticed the aluminum pitting in the lower half or base of unit. In addition to the pitting, when I use a towel to wipe it dry, a grey gel substance comes off on my towel. I'm actually planning on returning the unit. So disappointing.
