Well, about 2 weeks ago, I noticed the finish on my black SXMini M was pitting and coming off. I emailed the vendor (Yeti Vape) and YiHi.
When I woke up the next day I had an email from YiHI apologizing for my inconvenience and asking me to make a video of me scratching the paint with my fingernail. I made the video and sent it and a copy of my receipt to them. A few hours later I got a call from Yeti Vape and they explained that they were going to replace the unit with a new one with a different finish. I boxed it up and sent it to them on a Wednesday. That Saturday, I got a notice a package was heading my way. On Monday, I had a new unit in hand.
Where the 'bad' one felt smooth/slick, this one feels a bit rough surfaced, kind of like powder coating. I know it's not, that's the way the new finish feels though.
While I wasn't happy about paying the shipping back, it was nominal (<$6) and I have a brand new unit in the retail box, not some refurb or special 'naked' unit just for replacement use.
I'm well pleased with the response of both YiHi and Yeti Vape. I'm especially happy with the SXMini M!
