This keyboard is about 1.5 inches longer than the K360
I like the size of this keyboard and the feel of the keys; The mouse has a very low profile compared to most, but works well
The keyboard is used and possibly a return; I thought it would be new; It came with one AAA and one AA battery both used and not in any type of wrapper and fell out when I opened the box; This was to be a new item, not a used or refurbished item.
