If you look at the Sonic website, it's clear (to me) that they don't want to say where they're located. All they have is a contact link, including one for warranty issues. You might be able to lie and say you have a unit that needs service, and see if you can get an address, but otherwise they'd prefer not to disclose their physical location. They're also short one year of warranty vs. the DV, which is covered for 2 yrs.
I would only buy this model from a trusted dealer who will promise to replace the vape if it goes down during the one year warranty period. That would be a short list and I'm not sure anyone is on it. Vaporstore and VaporNation are two that carry it, but neither has any warranty info listed on it. Without a dealer to stand behind it, you'd be looking at shipping it back to somewhere in China.
