Echo this - I have 5 of these OG HomePods across two different places, and they've always "just worked" for me. Great multi-room audio, fantastic sound, and good for tasks like timers.
The biggest critique I have is that after relatively major OS updates, it may take a day or two it seems for them to get "in sync" and have stuff like multi-room audio work without funky issues.
Mostly happy about this announcement because if one of my HomePods break, I can get another one without risking a random eBay purchase.
