    Blissful sleep

    After having used a fan for years to produce white noise, I finally got fed up with all the dust and cold breezes in winter and bought this based on reviews. So glad I did. The machine is very small, inconspicuous, and easy to use. With the adjustable top and sides and high/low switch, users can find the perfect sound for their needs. It's small enough to pack in a suitcase and use on vacation. I have used this for a month now and am very happy.

    The Sleep Mate exceeded my expectations. Very southing and consistent sound. No complaints thus far. I suffer from tinnitus and this product cancels out the humming sound very well.

    Customer review by GoTeamVenture

    This noise machine is perfect. I am a very picky person and a light sleeper. We had been using a humidifier at night for white noise for the past 2 years but it finally gave out. We then switched to a Homedics tabletop fan. It really dried the room out and was way too loud. Another humidifier we own was also too loud. We contemplated an electronic sound machine (nature sounds, rain, waterfall, etc.), but after researching found that many of them turn off after 60-90 minutes or were poorly manufactured. We then decided to go with this one after reading reviews. We couldn't be happier with our choice. Runs all night, multiple volume/sound adjustments can be made. Sounds just like a fan/humidifier or blowing air but it doesn't blow any air. I was able to sleep better on the first night of use.

    My needs the sounds of a fan to fall asleep I hope this is cheaper then running the fan all night.
    by machineb 11/27/2008
    • Yes, absolutely. And I pay 36 cents per KWH, so I watch things closely. Also, with a conventional fan, your bedroom can get too cold half way through the night because of the fans air movement. This device adds no significant air movement to your bedroom.

    • Depends what kind of fan it is. This uses 40 Watts. So it is like leaving a 40W lamp on.

    • I would assume so given the small nature of the device, as well as ever changing energy conservation guidelines for manufacturers

    • I really don't no. We prefer it as you have basically the same sound, but no draft or wind. Just the soothing sound to sleep by. Carry an extra with us when we are away from home. Can't do without it. Thats why we now own 3.

    • I have found no difference in my electric bill and is louder and more effective than a fan for masking noises.

    I live on the 3rd floor of an apartment & am frequently awakened by the sound of slammed doors. I use a box fan but to no avail, I'm still awakened. Does this product mask the low sounds produced by a slammed door & what is the best location to place the device? Also, should I wear ear plugs to supplement it as well?
    by S1210201075 7/12/2010
    • I place it across the room on a dresser on the low setting. I can't hear the TV that is on upstairs when this unit is on low. I hope this helps. It was the best investment for me.

    • It should cover the door slam sounds. You can adjust the noise level on the unit two ways. The fan speed and the amount of air leaving the unit. Put it close to you and you will not need ear plugs.

    • It is highly adjustable, so you can set it to whatever tone you want. You may be able to find one that does the job. I have used it when someone in the next room is playing war games on their x-box and could not hear them.

    • The best place to put the device is directly across from your bed. The white noise has 2 levels to choose from and MIGHT block that of slamming doors. You could perhaps still feel the vibration from the doors slamming. My problem was the low sound from the boiler. I couldn't wear ear plugs because they hurt my ears after a while. I can only say to try it to see if it would work. Good luck.

    • I would put it on your night stand or dresser and I don't think you'll need ear plugs.

    • I live on the ground floor of an apartment and in the front so I hear the car doors with out it. If you want to put it across the room on high I dont think you will need the ear plugs. It does have ways to turn it up or down so you could find the right one for you.

    • anywhere in your room, on a dresser across the room is great, you can adjust the volume and the timbre of the white noise. earplugs are your call!

    • Yes if the device is at least 10 feet from our head.

    • I will block some low noise, but not all. It comes with directions on where to place it in the room you are using it don't worry. You might not need ear plugs, but I would recommend them for ear protection.
