Anyone has this subscription with the Fire tablet? Just saw Mrs Bee's post about this; I never knew about this!

We area total Apple family, but I am so tempted to do this later on when we go on longer trips. No need to worry about wifi or he messing up something on my Ipad; everything is "approved", parental controls, and content goes up to age 12. I can see each of my girls having their own instead of each having an iPad and the fee is so cheap!
