I know it looks like a cheap calculator, but it is so much more. This little guy, the Smart String, wants to replace your tape measure. The Smart String gadget has 50-feet of 20 pound string that you can use to measure just about anything. You can quickly get the circumference of an object, or the length. The measurement is displayed digitally to 3 decimal places.
In addition you get a calculator, a leveling bubble, and the ability to store 3 measurements. Perfect gift for just about anyone from a contractor to a college student. Yours for $14.95 here.
