My device broke in warranty (< 1 year). Customer support refused replacements, finally offering a 2nd-hand / refurbished replacement (illegal according to EU law).

Despite my attempts at polite out-reach to individuals at the company, including C-level, everything was ignored until a lawyer friend sent a formal letter - and suddenly everything was magically resolved the next day.

It's such an expensive device, and each press-release makes it more and more cultish - I couldn't recommend buying this - I'll wait for a competitor to do a better job.
