The tool works okay enough for zesting, but is terrible at peeling for cocktails or drinks that need a twist.  The scoop cutting device on my unit was dull and it did NOT cut into the skin of the lemons, limes, or oranges.  So, half of the functionality of the device is lost. Therefore, the OXO Lemon Zester is not worth the expense.  No matter how I held the zester or oriented the fruit, it didn't cut. I was left with having to find alternatives and the OXO zester is used only for the thin strips of skin used for recipes (not for cocktails).
