I’ve got two first gen HomePods here which died slightly out of warranty, and AppleCare wanted $300 a piece just to take a look at them. Makes me quite gunshy about spending yet another $300 on a product which may not last more than 2-3 years.
Here is a video, more on his channel
And I think it works out to about $80 once you include shipping. Ive got a dead one right now - trying to decide if I want to source air gun to fix it myself or just send it to him. Less than $100 to have it fixed is kind of a steal.
