I've been guessing my coffee-to-water ratio for months, and this spoon fixed it in one scoop. The engraved fill line makes it stupidly easy to get the same cup every morning without measuring anything.
The etched lines inside the bowl actually take the guesswork out of my morning coffee — one scoop of the ultra coffee concentrate, fill to the line, done in under a minute. The little bunny engraving makes me smile every time I pull it out of the drawer.
