I am not going to lie; I was rather intimidated by some of the mixed reviews of this product. However, the product I received was in excellent condition. There are a few barely noticeable scratches, but in overall fantastic condition for the price. The pictures taken for the product were taken using a 25mm lens on a micro four thirds camera. Some of the close-in pictures were taken using a 10mm or a 26mm extension tube to show the detail of the condition.The keyboard was in excellent shape. The keys looked untouched. All the resting pads on the bottom of the keyboard looked brand new. The only noticeable wear on the keyboard were some slight abrasions on the underside of the keyboard (hairline scratches) and some dirt buildup in the battery bay and the power button circles. All of the wear is minimal and unnoticeable unless inspected very close. The mouse, on the other hand, contained quite a few hairline scratches along the entire plastic based top cover and some black specs embedded in the surface. Again, this is not remarkably noticeable unless you have a light shining on it. The black specs were simple to remove and came off with some scrubbing.As for the functionality; both products work as expected. The keyboard and mouse connect with no problem. All keyboard keys operate smoothly, no binding or abnormalities. The mouse also works perfectly fine. My only quibble with the mouse it that it does not glide as nice in comparison to other mice I own. However, that is just due to its construction. The mouse has two long strips of hard plastic on the bottom of the mouse used to make it glide on the mouse pad. These rails generate more friction on the mouse pad in comparison to the standard alternative to four low friction, small contact pads on the bottom of other mice. The mouse gestures for scrolling and other features works great and make up for its high friction underbelly in my opinion. Overall, a great purchase.
