Product review (5 stars): Better than the Kaz and better than the one that ...
Better than the Kaz and better than the one that actually came with the unit. This one is thicker and doesn't flop over, fits nice and evenly all over. The Kaz I got before this one was not uniform in size so one opening was wider and it didn't fit right. I leave the unit running 24 hours during winter and fill the tank each night, and I haven't seen a change in the amount of water being used up between any of them
