Now here’s a product any control freak would love—the Waitek Shower Monitor. For any parent or sibling who has ever come at the end of the long shower chain only to find cold water, this is for you. It’s a very clear and very reliable shower control that gives an allotted number of minutes of water, anywhere from five to eight. Once those minutes are up, an obnoxious alarm sounds and cannot be silenced unless the water is shut off for two minutes. The noise alone would ruin a shower buzz. There is an LED display to tell you how many minutes remain and the temperature of the water. Talk about watching the clock! This could be the end of relaxing in the shower. On the other hand, it could mean hot water and justice for all. Costs $110.
