I’m a little concerned about not being able to replace UniFi equipment when it dies. After months of staggered purchases, my entire network is now Ubiquiti: USW-Lite-16-PoE at the core, USW-Lite-8-PoE at my desk, USW-Flex-Mini in the mancave, 2x U6-Lite-US (one on each of 1st and 2nd floors), and a USG. It’s a great setup, but boy am I concerned about replacing dead hardware… so much so that I have thought of getting a spare switch, AP, and USG – just in case…
