I upgraded to iPad OS 13 and it works great. There is a small scratch on the display if you look closely, but that's not a big problem for me, if you have a protective film you can't see it at all. The only significant point is that there is no original power adapter and charging cable, if this bothers you, be careful. In conclusion I have to say this is a really good deal, I can get $100 cheaper than buying a new Air3 and it works fine.
