Wholetones® 2Sleep Speaker & Music Player – Enhanced with Ancient Solfeggio Frequencies | Clinically Tested for Improved Sleep Sound | Long Battery Life

I just got it and am already going to rate it 5 stars. It's not made out of cheap plastic like I thought. It's made out of a heavy duty metal. I like it. The sound is great! Honestly bought for myself because of my insomnia and I don't want to keep medicating for it. Will update later if it actually helps my sleep.Edit: IT WORKS. I am a 34 year old adult. Not a child. This works on adults too.

Got this for my daughter who is 15 months and it’s perfect ! She falls asleep wonderful the sounds are soothing I have feel asleep listening to it as well. Only thing I would change is for it to go continuously instead of pausing for the next song/sound. Other then that it is wonderful!

Great volume options. Sleep timer mode for 90 minutes. Wonderful relaxing music in the key of David to South you to sleep! Love it!

Got this for my 4 year old grandson who was using another sound machine. Since using this he sleeps longer and not walking to bad dreams.

174 Hz, 333Hz, 396Hz, 444Hz, 528Hz, last one is 963~120Hz.Beautiful
