Query: really good

The mobile we had before I bought this one you have to manually turned it, like a music box. My baby loves it so much (she started to notice the mobile when she was about 6 weeks) I decide to buy a new one when she is 2 months old. This one can run 20 minutes. My baby normally gets tired of it around 30 min. So it is good I just need to reset it once.Highly recommend.
