can you know the Benefits of a Coffee Grinder?

there a article on Coffee Grinder,as follow:
The benefits of a quality burr coffee grinder are enhanced flavor, custom grinds that don't give your coffee a bitter or burnt taste, like blade type coffee grinders. They are much quieter and less messy, and built sturdy for years of use. For those that love fresh tasting coffee, a quality burr coffee grinder is a must!
The benefits of a quality burr coffee grinder is that not only does it not over-process by heating or burning the essential oils, but the grounds are consistently even, whether you prefer a course or fine grind. Because a burr coffee grinder runs at a slower speed, it does not overheat the coffee beans like a bladed coffee grinder does.
Burr coffee grinders can be adjusted for course or fine grounds, depending on the positioning of the burr or the metal discs that do the grinding. There are two types of burr coffee grinders-a wheel burr or a conical burr.
A Wheel Burr coffee grinder is the least expensive but they can be quite noisy and messy. The wheel spins very fast to grind the coffee, and they are more prone to clog than a conical burr coffee grinder.
at last,I'll say my idea:Coffee is good drink for the peoples who are tired.Appropriate amount of Coffee is good for our health.
