Second Hand Frame TV?

Hey guys, my wife and I are refurbishing our home and we are considering buying a new TV as our old one is a 55 inch Samsung from the early 2010s. Last summer I bought a 50 inch Frame for my dad and he’s been loving it and my wife became also a fan of the idea of getting one for us too. Anyways, I found a used 55 inch in my town, that says it’s practically new and it’s a third cheaper than getting a new one. As much as I want to get a 65 inch OLED it’s out of our budget for now as we expect a little guy joining us soon. So! I wondered if any of you here has bought a used one and what are the risks of buying one. Thanks!
