Yeah, I feel like Ten is a good age. I got my oldest, his first one at Ten. I feel like he was mentally mature enough for it, and I feel like that's really what you can base it off of. If you, they're immature and you feel like they're going to break it, well then no. Obviously not. Wait, so they're a little bit older. My mom didn't get me a phone and so I was 17. So mine's pretty damn lucky
