Don't waste your money
I enjoyed my Eight Sleep for months, but then something went wrong with the system and the noise the fan makes is not so loud I have to wear earplugs when I am using it, which I now can't every night due to noise. I have shown videos and swapped numerous emails to Eight Sleep but they just keen saying it is 'normal' (it most definitely is not), and that to contact again if anything changes... Wtf. Terrible customer service, really disappointing. Don't waste your money.
