First, there were the keys themselves. When you look at most keyboards, and focus on the keys, they are almost recessed into the board. They protrude, but the keyboard itself is primarily one piece of plastic. If you wanted to remove a key, whether it was for cleaning, or it was simply stuck, you’d often have to pry it off the board. That isn’t the case with this keyboard. The keys stick out from the board.
You can grab each key with relative ease, and pop it off with little to no force. They also go on REALLY easy! You don’t have to maneuver any pieces of metal to stick into hard to reach holes, or worry about whether or not it will make contact. Under each key is a plus sign that fits into the key perfectly.
