we have 2 I really bought them as a device that could be locked down to just books/audio books, and they work for that. They def aren't a substitute for a tablet, and we have the browser feature disabled. I wish I could say I use the parental controls to monitor how much they read etc. but mostly during school my kids were doing reading through the school programs like Epic etc and we've not pushed reading since school got out between all the audio books they've been doing and other activities. We don't do anything else with them, but when the kids are home and it's not screen time they are pretty much listening to an audio book on their own volition. No questions asked 2 year warranty was truly no questions asked after DS submerged his. They've gotten me more hours of "getting something done" than I would have gotten from a babysitter for the same price so even though they aren't amazing they've been worth purchasing for us.
