I tried to find a thread on shower times and if anyone had used a device that is suitable.
We have 2 teenagers and it drives me crazy on how long they take in the shower, I've tried the timer that beeps in ever increasing loudness - worked for about a week, turn on the hot water in the kitchen - just prolongs it even more, screaming at the - just gets my blood pressure elevated!
I have seen this, is anyone using one or anything similar?
