Garmin Edge: Chinese vs US versions

I found a Garmin Edge 850 on FB marketplace. I know, buying second hand devices off the internet is sketch. The seller has a Chinese version, so the box has Mandarin characters on it, etc, but I ran the serial number on the Garmin website and it came up with a computer, so it seems legit. Are there any actual differences between Garmins sold in China and the US? I’ll be able to change the language to English
