I have an older Razer Blade 13 that was a replacement for a lower end model that had battery issues. It was well within the warranty period (had it less than two months). I had been emailing their support for a couple weeks before getting tired of the wait and just tagged them on Twitter and asked for help. Had a replacement in less than 48 hours. Their actual support is trash, but the social media team seems to be the way to go when it comes to getting actual help.

EDIT: For clarification, I sent them back the bad one and hadn't heard from them for awhile.
