Sovol’s official site is https://www.sovol3d.com/ as far as I know.

I don’t think your site is legit, it looks like a blatant copy of the actual site to trick people into buying through them instead, which may well be a scam.

I’d recommend always buying direct from the OEM or official distributors (unless you are buying a used machine). Sketchy third party sites tend to have poor customer support and may leave you ineligible for any manufacturer warranty.
