Bests & Worsts Reviews from Amazon

Let me preface by saying we use WiFi at home. Let me also say I have a Kindle Fire HD. Im not aware of any issues as I haven't read the reviews on this... so I can only explain that my four year old loves this app. He has access to many PBS shows and they feature different shows every week (so ive been told) My son is fairly easy to please. I have seen the Super Why Halloween show 6 times in the last day :) Its easy to run, doesn't eat alot of memory.. and has a simple user interface for him. I couldn't be more pleased. The downside (even though it doesn't bother him or I) is you dont get that clear HD picture. But it's not a deal breaker for us.
