Love this sound machine. Used it every night for 15 months. Then all of a sudden it won’t charge or stay on for more than 30 seconds. I’ve tried new cord, different outlet, tried to take apart and can’t seem to get it open. I’m incredibly sad about this! My nephew has the same one and was good for years!It works great and is easy to pack but the clips (I use thunderstorms) have about a 15-20 clip that recycles instead of a full minute or so therefor it gets repetitive quickly.It works well and our kids and us use a lot. Perfect for traveling as it can be charged and used wherever.I have ADHD and my entire life falling asleep has been a struggle for me. I have a hard time shutting my thoughts "off" and going to sleep. Since trying this sound machine for the "brown noise" I've been able to shut my thoughts off and fall asleep within minutes every night. I love that it's got a built in batter. My power has gone out and yet this will still work regardless. Absolutely the best purchase I've ever made for my sleep. 10000% recommended!The sound on this device is so crisp and clear. I love the pink and brown noise options, they’re so soothing!I use this in a old wood frame building where you can hear everything- the garbage truck at 5 am, people walking down the hall, talking, peeing in the toilet upstairs (gross). I couldn’t get a good night’s sleep to save my life. I was desperate so I got this based on the reviews. I love it! I use the “therapy” setting that has 30 minutes of rain and then “brown” noise for the rest of the night. I have it pretty loud (sounds like an air purifier running on high), I tried out the different noise types (white, pink, brown- who knew there were so many different types?) and different volume levels and finally found the right combo that blocks out about 95% of the noise. Now I sleep like a rock! I’m pretty sure they could be demoing the building and I could sleep thru it with this thing! Not really, but you get the point.I love this sleep machine. It also works great for the dogs and for the great grand baby when I keep him. All of us get better sleep. It also works for drowning out sounds of thunderstorms and fireworks which affect one of my dogs. It's portability is great for travel.Great product!Needed this item to help me fall asleep. Did not work for me at all. This does not mean it would be the same for you so, you would need to try this for yourself. I had read an article and thought it to work. I was so excited and expecting it to be wonderful, unfortunately it was not for me, but you do need to try it for a few nights.I contacted the company and they were marvelous. They were sad it did not work for me, but, were very happy to return my money on receipt of the item. On receipt they refunded me in full. I think that is an excellent thing to do, so I they deserve all my praise and would purchase other items form them. They get a GOLD star from me.Bought for my wife who is undergoing Chemo and was finding sleep difficult. She finds the meditation setting very helpful. We have no regrets about buying and would recommend.Got it for the baby room and it works great. It also has powerful volume so we try to keep it on a low setting as it can go high easily. The battery works great and I love that it is rechargeable and movable.This product is greatIt’s small does not take up roomThe sound and controls are very easy to workMeditation sound is great fast asleep in no timeWould recommend this to anyone that had trouble falling asleepThe product was faulty. I returned it. The cost was refunded but not the postage.
