The DaysAgo digital day counter is a real kitchen gadget. Imagine you open a jar of pasta sauce, use half of it and then put it back in the fridge. You stick a day counter on the lid and push the button. From that moment on the display on the day counter will show you how many days it has been since you opened that jar. Very simple, but also pretty smart. There are two versions of this gadget; one with a magnet and one with a suction cap. And its use doesn't just stop in the kitchen. A day counter could be pretty handy to check how many days it has been since you fed the fish, or watered that plant.

The DaysAgo day counters are sold for about $ 5,- a piece in packs of two.
