In a world where we know how many steps we’ve taken in a day and the specific firmness of our mattress, why not extend that precise knowledge to our showers?

This Techoss digital shower thermometer monitors the water temperature in real time, letting you find exactly the perfect temperature for you.

It is also a great product for parents, who can monitor the temperature before their easily-over-heated toddlers get in.

Today, it’s just $17, which is the exact price we want it to be. Well, it’s the lowest price we’ve seen, but you get where I’m going with that.
