We gave this to my son for his 4th birthday, and he loves it! He loves to read books, and he is starting to read a little bit, so it seemed like the perfect system for him. I made sure to download other books before reviewing this, and it was an easy process that took about 10 minutes to get everything set up. Now that it is set up, it should only take a minute or two to get new books on it. I'm a little disappointed about it only holding 5 books or activities at a time, but given that it's pretty easy to add and subtract them it's not a huge issue.
