These have been discontinued by Apple. If you really want all Apple hardware and want to expand your WiFi network, get them now. They will not be available for much longer.
Apple branded router? I guarantee you can get a MikroTik that will do twice as much for half the price.
I put one of these halfway to the back of the house because the wifi was weak in those rooms. I created a “roaming” setup so that when you left the zone in the front, you were automatically picked up at the back. Trouble free and well worth the price.
