Product review (4 stars): good buy
4 in the box.  Each wick is a sandwich of standard material with aluminum reinforcement in the middle.  It looks/feels fine after several days.  Replacing Kenmore consol wick, which is way over-priced.  The new wick fits snugly in the compartment and I am using one each compartment (2), placed on center.  I can feel the added moisture when compared to running the fan without a wick.
I am also using Holmes bacteriostat, so I will be looking for the cheapest wick and cut it fit or live with some smaller sizes.

edit 4/28/15:  Used 2 over the winter.  They worked well and no slimy feel anywhere, water, wick and the console body.  I'm ordering these again and plan to use them in the Stadtler Form oskar humidifier as well.  I can cut them to size.
