The Dreams Ban Clock is an interesting alarm clock concept- the alarm goes off and it won’t stop until you insert a coin into the clock. The clock (I guess it’s a bank too, technically) can hold up to $25 in quarters, less if you cheap out and put in pennies or nickels. So you’ll also be saving some money every day.
This is a great idea for a guaranteed wake-up as long as you don’t keep a stack of coins sitting right in front of it. If you keep your coins elsewhere, you will have to get up to find one to plop into the alarm to shut it up. And if you can’t find a coin or don’t happen to have any left, you’ll probably have to get on the floor and unplug the alarm. Which will definitely get you up!
