I've been running the original Unifi Dream Machine (the can, not rack) since it released in 2019. Been pretty solid, no complaints; it replaced my trusty Asus RT-N66U w/Tomato firmware; I think the UDM has been deployed longer than the Asus at this point.

The single built-in AP on the UDM was getting a bit overwhelmed, so recently I bought a U7 Lite AP to help split the load a little better. Working great so far, but now I'm looking into adding an NVR for cameras.

I like my Unifi setup, I’m just scared of a rug pull.

Same here.
