I wanted to share my customer experience with vaporshark the other day. I emailed about my vortice rda having a striped post to see if I could send it back to get a repair. Free or paid for by me would matter just wanted it fixed. I got an email back from them saying sorry about your problem but we don't fix them. So pretty much sorry buy another one for $70. That kind of sucks. Dotmod on the other hand had a similar problem sent it back had the new version in 5 days now that's customer service.
