Extremely well thought out design for the easy and efficient squeezing of limes. Had one almost identical to this one (maybe an older version) and I just plain wore it out. Be very sure you use it correctly because it's counter-intuitive. My wife tried it and said it sucked. That's because she had the lime half in upside down. One looks at the round contour and thinks, obviously the round part of the lime half fits into the round part of the device. That's backwards, the flat side of the cut half lime faces the curved in contour towards the juice holes. Works like a charm when used properly.
