If you have to know every tiny detail of your waist size, this is the gadget for you. No pound will go unnoticed with this one, you can even subtract 1.5 centimeters if you happen to be wearing a shirt at the time of measuring. The tape’s range is from 50 on up to 150cm. It requires 2 AAA batteries to keep it up and running. All you need to do to get one of your own is pay the clearly affordable price of $448. Personally, I think I’ll just stick to my non-digital measuring tape at that price.
