Anecdotally, Amazon’s Fire tablets seem to be incredibly popular kids’ devices, so it makes sense that Amazon would make a model just for them. The Fire 7 Kids Edition comes with kid-friendly content subscriptions, a rugged case, and most importantly, a two year warranty that covers accidental damage.
It normally sells for $100, but Amazon’s marked it down to $70 today, the same price we’ve seen seen in early Black Friday ads, so there’s probably no reason to wait for a better deal.
