Hamzer Electronic Keyboard Piano Unboxing (Used)

I (somewhat accidentally) bought this Hamzer Electronic Keyboard Piano though an auction on eBay. This video starts with covering the unboxing, explains the different parts and assembly of the stand, and gives an opinion on whether its worth it to buy used keyboard pianos on eBay.

Do you have any starter questions on buying a keyboard piano or Ukalele online? Let me know in comments.
I'm also pretty new to musical instruments in general. So, if you have insights to share that will be helpful for other viewers, let us know in comments too.
