Looking to purchase a 2022 Vestaboard from a local seller... anything I should be aware of?

I read in another post below about older HW revisions requiring upgrades in order to use newer FW. Is 2022 model OK?

Seller says it is new in box. Anything I need to ask or be aware of before buying it?

Thanks for any feedback. I live in the SF Bay Area in case there are other folks looking to sell theirs.
