Query: Good Sound/Music Options

Easy to use. Sound and music options are very nice. You can adjust the volume and the lighting, and timer. I use this for my infant, toddler, and my 8/10 yr old boys who are used to music or white noise. The only cons are it doesn't take batteries, so it needs a power source at all times. It comes with a USB cable that can be used with a simple power plug/adapter (like for your cell phone), but doesn't come with the power adapter. Luckily, I have many extra around the house. Again, wish it worked with batteries so I could it without power, but other than that it's great and my all my kids love it and fall right to sleep.
