My 6 year old was so happy to have his new tablet. Somehow while 'hugging' it he opened or closed the built-in stand and it pinched the flesh on his chest. The bruise is about an inch long and 1/4" wide. It started out red, turned purplish in the time it took me to calm him and sit down here, and will likely be dark by morning. It's right by his <nixxle> so I'll wait until he's sleeping to take a good picture I can crop.
Probably a one in a million or more occurrence, but definitely NOT for children under six no matter what, as suggested. As far as the "Pro", I haven't had time to set it up for filtering or to explore the other Pro feature.
The protective case is definitely "cooler" than the little kid cases, and he's experienced enough (14th (?) fire tablet between 2 kids) to be responsible for the 2 year guarantee (not the first of those).
Anyway, I let my boys play rough and tumble but I didn't expect my youngest to scream out in pain and throw down his new tablet before I even turned it on. After calming him (he's tough and resilient) he said he hated it and didn't want to touch it, ever. A few minutes of big brother holding it fixed that, but still...
