The way to judge if the Xhorse seller is official or unofficial: Price, certificate, software/firmware update, users’ reviews. etc.
Here we go one by one.
Original Xhorse VVDI tools are made good of quality at higher price.
This is easiest way to get it, just browse the site, click “Contact us” to ask to send you.
3. software/firmware update
Only the original Xhorse VVDI2/VVDI Pro/VVDI MB BGA tool/VVDI key tool can update software/firmware online, the copy ones won’t work. Suggest you go through the whole site
to check if their description and tech support column announce the update.
4. users’ reviews
Xhorse reviews are most trustable, especially if users give reviews on the most reliable forum http://www.digital-kaos.co.uk/forums/, search “Xhorsevvdi” you will find many posts are talking about xhorsevvdi.com.
