NOTE: This keyboard only works for Macs with Intel processors (models dated approx. from 2006 to 2023).
This keyboard is well designed so that makes it very easy to type. It never needs batteries or recharging. If it runs out of juice just put it in the sun for a little while. I used the keyboard for years in a room that didn't have a lot of light and only had to put it in the sun a couple of times. (You may have to put it in the sun when you first get it.) It has a number pad and foldable feet (see photo 3) and comes with a dongle (see photo 5).
Note that the hight below is when the feet are folded; hight with extended feet: 1".
