I bought a 2020 laptop pro and unfortunately 2 days after the warrantee I spilled a tiny bit of water on it and it died. Thankfully my home insurance covers this, but guess what? They removed the serial number! Not only that, but getting any kind of response to help with any legit certification of what this laptop was is impossible.I really do not recommend buying these 2nd market laptops with the seal number removed. I mean wtf? Unless youre fine with never having any kind of recourse. Huge risk.
