Product review (5 stars): The good one
After trying a cheaper pad, I went back to the April Air pads. They cost more but they last longer before scale buildup happens. I get about three months out of the April Air pad and only a month out of the cheaper pads. So even though the April pads are more expensive, they are cheaper in the long run. If you have hard water, pad life is short anyway, so this better pad is the way to go.
