So I bought the K70 Cherry Brown version 4 months ago now and around a month ago my keys started repeating and often taking several presses to work once. I've cleaned this keyboard out thoroughly twice in the past month and it definitely helped to a degree, but ultimately the problem is still here and it's becoming incredibly irritating. I never thought there was any firmware out for the K70 but I've read in a few places there is now and I'm wondering if this could be of use? Hope to get some replies. Thanks!
