The only thing that worries me about this machine is that some reviews say it can stop working suddenly after a few months. This machine has been so great, I would hate to have to be without it while a new one was shipped. Hopefully, mine is OK and will work for a very long time.We have been married for 40 years. My husband snored on and off for most of the time. But it was never a real problem and a nudge would get him to turn over and the snoring would stop. However, over the past year, his snoring has gotten very loud and is very constant. He snores every night and a lot of the time it is 'buzz saw' in loudness. Turning and changing position does not do anything to help. He tried the nose strips, but that did no good.It was a difficult situation as although he was the one snoring, it really was my problem as I was the one who could not sleep with the noise. I researched various snoring solutions such as mouth pieces and other devices that might help snoring. But even though he appreciated that I could not sleep, he is not the type to be gung ho about finding a solution or purchasing and trying some of these devices. His basic 'answer' to the problem was that some day his snoring would stop. After a year, I really doubted that was going to happen. I don't think he appreciated how totally his snoring kept me awake with so many totally sleepless nights! He was the snorer, but it became my job to find a way to deal with it.It came to the point that we had to sleep in separate bedrooms most of the time. Our kids are grown, so we did have a couple of empty bedrooms to use. Although I could get a good night's sleep, a separate room was not a comfortable solution overall. Also we travel a lot and have to use the same bed when guests come to our house. So I had to find a way to deal with his snoring when traveling and at home.I researched the white noise and sound machines. This one got such high ratings I figured it was the one to try. From what I had read, I thought the actual 'white noise' would be the best. But I am so glad I bought this one that had many sounds.The machine has done it's job almost from the first night we used it. There was one big adjustment however. The first night I put the machine on my nightstand. It helped somewhat, but since the snorer was on the other side of me, I could still hear him quite a bit. I read about these noise machines and it said to work best, the machine should be between you and the noise. Thankfully this machine is not very large. So I actually placed it on the mattress up against the headboard between my husband and myself. Now the sound is truly between me and the source of the noise. I placed it so the controls are at the top of the machine and I can easily push the buttons to adjust the level of sound. It only takes up a little more than 4 inches of space and on a king size bed, that does not bother us.In testing out the various sounds, I actually found the basic white noise to be rather irritating. I like the rainfall sound the best. I put the richness setting at level one as it adds a little diversity and a rumble of thunder once in a while. I have awakened at night several times to think it was actually raining before I realized it was the machine.I play the machine all night long. I think your mind adjusts better to listening to the sound when it is on all the time. I start out at a minimum level. But when the 'buzz saw' starts, I crank up the sound until it drowns out the snoring. It does take a little adjustment to get used to the rain sound constantly and especially when I have to make it very loud. But the adjustment has been quick and relatively easy and allows me to get a good night's sleep. Part of the problem with the snoring was that it could be extremely loud one minute and moderate the next. The constant change in noise levels really had me edgy and nervous as when the snoring was quiet, I kept mentally waiting for it to get loud again. My nerves were always on edge wondering what level of snoring loudness would be next. With the constant level of the rain fall noise, it helps me to not worry about the level of snoring noise. If the snoring gets loud enough to wake me, I now just amp the rainfall level up a few notches (sometimes more notches than than 'a few') and I can go back to sleep.I read some of the reviews that said the machine was not loud enough. I can't help but agree with other posters that those machines must have a defect of some sort. When I put my machine on the loudest level, it is extremely loud. Even with my buzz saw, I never need to crank it up to the loudest level. I am happy that this machine is small as we will need to take it with us when we travel.I do hope my sleep machine lasts a long time. But whenever it does stop working, I will be getting a new one. It really has been a wonderful device to help with my noise problem. I don't think I really thought it would work as well as it has and solved our situation so easily.
