I had 2 K70's and 2 scimitars. The lights broke on the k70 twice and they just said tough shit the second time cause a warrantied k70 only gets 90 days of coverage and it broke a second time after ~120. And the scimitar got warrantied too and the second one at least lasted ~3 years. I've since sworn off everything Corsair
How old? My first one would've been around 2015-2017. I forgot to mention it'd also occasionally double tap buttons too but it was near impossible to replicate.
