Review on Stainless Steel Citrus Zester & Cheese Grater - Razor-Sharp Blades For Parmesan, Lemon, Ginger, Garlic, Nutmeg & More Fruits/Vegetables - Protective Cover Included (Purple) by Anden Turn

This device works fast because it is sharp.I used to struggle to grate lemons but not with this device. It is very easy now.The length of the device also helps keep your hand away from the grating area (which is safer) and also gives you more grating length per stroke so it goes quickly. The device holds the zest on the inside. (My concern before buying it was wondering if the zest would get all over because the device is long. This doesn't happen at all.)It's the best grater out there, that I have found.
