After opening the lid one day there was a loud crackling noise and the speakers were both blown. To repair it, the Apple store had to replace the entire top case (top half of the chassis including keyboard, trackpad, speakers) and also replaced the battery, which would have cost ~£500.

I got it back two weeks later after dealing with a smug 'Genius' who treated me like an idiot. He also claimed that the software diagnostics were clean, so there was nothing wrong with the laptop. I had to drive 1 1/2 hours each way to the store for a second time during business hours just to argue in person with them, because the speakers were clearly broken.

The exact same problem happened twice more over the next year, taking two weeks to fix each time. The final time was outside of the 1yr AppleCare warranty, and they wanted to replace the top case, battery and logic board for ~£800.

Coupled with the useless touch bar, 16GM RAM cap, awful display scaling issues/confusion when external monitors were attached, sluggish performance for video editing and OS updates that broke the machine, it convinced me to avoid Apple products completely.

I got a full £3100 refund after 18 months under EU consumer law and build a powerful desktop PC (16 core ThreadRipper, 32GB RAM, 1080ti) with £1500 left over.
