I thought that this would help maintain my priorly heated water warm, but it does not. All this is equip to do is bubble, but I suppose that is fine so that you do not stay with you feet placed in this forever.The bubbling feature is pretty great. But it you do not want to have cold water by the end splurge and spend the extra 15-20 bucks and get the other machines.
