If you want to receive and read notifications from your phone on your wrist, don't waste money on the gigantic Ionic or Versa. The only difference functionally is that they store music in them so you can leave your phone at home when you go for a run. I don't go for runs and I don't have a gigantic accommodating wrist for those things.
