Is Jumperroo useful for our babies? I heard its fun. When can we start using it for our LOs?

I have read that Jumperoo, like walkers, may hinder baby's development. Think it is generally recommended that a child should not spend more than 20 mins in one and always under adult's supervision. I think for jumperoo, it can be introduced to babies who are able to hold their heads up, which is usually around 4 to 5 months old.
