Query: MICROSOFT NATURAL ELITE KEYBOARD

THIS MICROSOFT KEYBOARD IS THE MOST RELIABLE, DURABLE, AND COMFORTABLE BOARD I HAVE USED IN ALL THE YEARS I HAVE BEEN USING COMPUTERS. THE ONLY REASON I HAD TO REPLACED MY PREVIOUS KEYBOARD,(SAME MODEL) WAS DUE TO A FRIEND WASTING AN ENTIRE CUP OF COFFEE ON IT. THE KEYBOARD POSSESS ALL THE KEYS THAT MOST PEOPLE WOULD USE. THE MONEY I SAVE FOR A NEW KEYBOARD WITH AMAZON VS EBAY WAS AN EASY 50% SAVINGS. THE COST OF AN USED BOARD ON EBAY WAS EVEN HIGHER. AS ALWAYS I RECEIVED THIS AND ALL MY PRODUCTS WELL AHEAD OF TIME WHEN PURCHASING FROM AMAZON. KEEP UP THE GREAT WORK AMAZON.
