Efergy Showertime Shower Timer & Alarm

This easy to use, battery operated, shower timer allows you to monitor the amount of water you use at every shower. Quickly and easily calibrate it to your shower by using the measuring bag supplied. Set your own taget. We recomment no more than 9 gallons or less than 5 minutes. Use the lanyard supplied to hang it up in the shower, or affix it to the wall with the suction cap. Turn on the timer every time you shower and follow the progress on the visual display. The alarm will sound when you have reached your target volume of water.
