Thanks for making me aware of it. I've been looking for something to get my 6-year-old nephew that can be set up to be kid safe, and I hadn't really thought about the Fire tablets until now. How's their durability?
I don't use unlimited, I've side loaded play store, set age range, enabled full parental controls on play store and on the tablet themselves... They have full control, but web is blocked etc. Play store is great, tells them they need to uninstall things to install the next game. They don't need my interaction to install X or Y now.
They did manage to download an app that let them have full access to unfiltered youtube, but we caught that pretty quick. YouTube kids is great as well.
The Kids Edition of the tablet is more expensive, but comes with a very rugged case and a "If they break it, we'll replace it. No questions asked" guarantee for the first couple of years.
Amazon's customer service is beyond legendary.
