Out of the several Bluetooth-capable devices in my house, the only thing it can connect to is my Samsung phone. I fiddled with the connection settings in the adult profile to no avail.
It's not super easy to use an external storage card, either. Installing and uninstalling apps is a pain when you have to keep switching between the kids profile and adult profile.
Other than that, it's not a bad tablet for kids. The rubber case is very sturdy.
I wonder if the newer versions have some of those bugs worked out. Maybe for the next one, I'll try an android device instead. My kid is getting older and probably doesn't need all those safety features.
