I am so impressed with how easy these are to play with and how well my 5 months old loves them. I wasn't sure if I was going to get him to like them but he is able to use his feet to knock them down and he loves that fact he can do that. The packaging is very easy to open and is very simple to use. I think this is a great deal and an awesome toy once he gets older I am excited he will be able to roll the ball to knock them over.
