Apple AirPort Extremes and Express base stations - set of 6

This is a set of 2 Apple AirPort Extremes 2 Tower model extremes ( the one with the label is a Time Machine) - Time Capsule (Flat Square Models): The two flat white square units with the central Apple logo are older generations (likely 4th or 5th Gen) of the Apple AirPort Extreme.  Apple AirPort Extreme (Tower Models): The two tall, vertical white towers in the background are 6th-generation AirPort Extreme and Time Capsule units featuring 802.11ac Wi-Fi technology.  Apple AirPort Express: The two smaller, palm-sized white blocks resting on the floor to the left are the 2nd-generation Apple AirPort Express base stations.  I have just disconnected these units bc I have revamped my home professionally.  I have been using these with no issues.  They work great.  They are obviously no longer available, nor supported by apple.  I connected the Time Capsule to my router, hard wired the other 3 extremes, and wirelessly used the extremes.
