I've been using it for about 3 years since I got it refurbished and it still works well. The only thing wrong with it is about 10 months ago I dropped it and the corn screen cracked and shattered (only about 2 inches though). It is on iOS 9 I think and is fairly fast and the battery lasts decent. It's from 2011 though so it's like 8 years old (it is not a iPad Air 2) it's the iPad after the original iPad. Is it ok to keep using I feel it's outdated and might catch fire while charging or something?
Added (1). I meant CORNER not corn lol
