Query: Disappointed

We had a Playard with a vibration unit and it worked so well that I wanted to have vibration for the crib as well. However, this product did not work. If the vibration unit was more than 2 inches from the base unit, it stopped working. I called the company and they said that the problem was due to interference and it could be from a baby monitor, cordless phone, hair dryer, the neighbors, or just about anything. Yet my cordless phone and baby monitor work and this product does not. The company suggested that I return it to the retailer. The music is also poor quality so I would not recommend it for that either. Very disappointing.
