Query: Not a Good Idea to Purchase!

I was disappointed that my sound shell appeared to be so cheaply made. The sound kept stopping after three minutes. I put fresh batteries in the machine and the problem continued. I repositioned the batteries and started the machine again. The machine started to smoke and nearly caught on fire. If I had been asleep at that time, I would have had a fire in my bedroom! Fortunately, I was drowsy, but awake enough to smell smoke. Needless to say, I am throwing this product in the garbage. I would suggest that no one buy this chintzy Chinese safety hazard.
