I had a problem with my Vaporshark DNA 200 battery, completely died and stopped charging and out of warranty. I was going to send it in and have them and have them do the $30 diagnostic.
I saw the upgrade service on the site along with the ultimate upgrade option to install a new battery and connectors as well for $20 more. For $70 it was completely worth it, and after I purchased, I saw sold out, so I was kind of cringing that they were going to tell me they couldn't do it. I shipped it out on a Friday, had it back by the following Thursday. New Chip, new batter, new 510, new connectors, back in business, plus my warranty is in place again.
Looking at the site, it appears to be sold out again, but totally worth it when it comes back up.
