I enjoy searching for the perfect sound machine and have high standards when it comes to noise. It's difficult to find the perfect fan or white noise, especially when traveling. At $20, this sound machine is a good option. The sound quality and variety of sounds are good, and the battery life is impressive. It can be used with batteries or plugged in, and the buttons are easy to use. However, I wish it had a light, and the power and timer buttons are small and located on the back of the machine. The organization of the sounds is also a bit odd. Overall, it's not my favorite sound machine, but it will work well for traveling.

This item is great because it is rechargeable, making it convenient to set it on my nightstand without needing to plug it in. It offers a variety of sounds and music with volume control and a timer. I enjoyed trying out the different nature and white noise sounds on my video, and appreciated the wide selection available.

Overall, the machine functions well and has real buttons on the top for controls, with the play/pause button also serving as the on/off switch. The speaker is located on the top and has a good volume range. It also has a long battery life and is portable.

However, there are some minor complaints. The timer button is small and located on the back near the cord, which is inconvenient. There is no light to indicate whether the unit is on or off, and it can be confusing to turn off the unit from the surface. Some of the sound variations are assigned oddly to the buttons, such as a sonogram/heartbeat sound on the Rain button and loud jungle noises on the Baby button.

This is our second time purchasing this white noise machine. Our first one lasted for years, but eventually stopped working earlier this year. Unfortunately, the second one stopped working a few days after we received it, but we were able to easily exchange it. The replacement they sent is working well and has been in use for 2 months. It produces a consistent noise similar to a fan blowing, which is great for keeping a steady sound to help with sleep. The older model had a two-speed control, but I only used one setting, so I opted for the single speed option this time. You can also adjust the tone by twisting the machine slightly. I would recommend this product to anyone who is a light sleeper.

These are placed in every bedroom in the house, there are about 6 of them. They effectively block out external noises and help with sleep. While newer options are smaller and offer volume control, these original ones have lasted for years.

We have purchased a lot of these and are about to order more. Placing 2 or 3 of them strategically around the bed creates a peaceful bubble of noise-filtering. I have been able to sleep through road work, construction, and a neighbor's noisy dog. My partner works nights, so daytime sleep used to be especially difficult. We have also placed them in the rooms where our dogs sleep and they no longer react to neighborhood sounds. If you live in a busy area, these are a necessity. They are also easy to take with you when traveling, I have even brought one to the hospital. I often recommend these to others.

I used a phone app to measure the ambient volume of the room from about six inches away. The ambient volume was 48.35dB and with the machine turned on, it was 64.35dB. This results in a 16dB increase with the machine at full volume. Overall, the machine is quieter than expected at full volume compared to my phone. If you're curious, I have also attached a photo of the inside of the machine showing the fan.

This item is an amazing purchase for our toddler's room. It helps drown out the newborn's fuss at night so our toddler can fully sleep through it. There are a wide variety of sounds to choose from.
