Query: I don't understand all the good reviews

After reading all these great reviews, I made this buy. This product did nothing for either of my babies-- in fact it made them fuss, which was not their normal behavior. It did not move fast enough at all! The swing is far superior, so I don't get the point of having this. It takes up too much room as well. If it moved a lot faster or vibrated, it might be useful, but I wouldn't recommend this at all.
