I have 10 Homepods, all in Stereo Pairs in 5 different rooms, 6 x G1 & 4 x G2. They all worked well until about 3 months ago, when 2 of the G2 Homepods failed with touchscreen issues, like they keep starting to play music by them selves, after resetting them, one started working again but the other one went into an endless loop of restarting like the touchpad is constanly signaling it is touched. After some research I managed to get it reset & updated it using the "Cover the complete Screen with Tape trick". They worked for about 5 days & started to open music in the middle of the night again. Now I isolated it to one Homepod that is doing that so it is currently turned off, but the second still has a flaky touch panel.
I took the worst one to Apple & they said they don't repair them, but would give me an exchange uint for about 7% less than buying a brand new one, which is not a very good deal as far as I am concerned. I showed them my Apple account on the phone where I have 33 Apple devices all active, but they didn't seem to care. So the G1's are rock solid, but now im waiting for the other 2 G2's to bite the dust. Won't be buying any more.
