We had a groupon for some and they were ok. I did them when my son was about 1.5 and he liked the open play time better. Not sure I would pay full price for them.
I did he little gym with Ava. Honestly it's very cute but so overpriced. Maybe when they are older it would be more worthwhile. I took her from like 6 months through one year.
