I have always needed some sort of steady noise in the background to help me sleep. Typically I have a box fan, ceiling fan, or circular fan running in my bedroom, but when on the road it is not the most convenient thing to travel with. I have tried using apps on my phone which usually lead to hearing the loop sound or other interrupting sounds that end up disrupting my sleep. Nothing like a notification coming through when you can't mute the phone as you need the sound. Also, the AC in a hotel usually has a mind of its own, cutting on and off at random times. However, the LectroFan is small enough to pack away and provides a perfect, non-stop sound that sounds very realistic. So realistic that I could have sworn that there was air coming from the direction of the sound. It also has some weight to it that helps keep it in place on your nightstand.
There are 20 different sounds that can help meet anyone's desires, as listed in the picture. These sounds range from the sound of leaving an old TV on to large industrial fan, like you're sleeping in a warehouse. After listening to all of them I almost wished they had a diesel generator sound to remind me of my times out in the field during training exercises.
The buttons are far enough apart and simple enough that it is easy to make changes in a dark room. There is a 60 minute timer that can be increased per 60 minutes to 120 and 180 that I do not use, because when the sound stops, that is when I wake.
The other thing that this device can be used for is drowning out noises while you are awake. When used in an office or waiting area, the volume can be increased to a point that you can barely hear yourself talk over it. Yet, at the right level and setting it can prevent anyone else in the area overhearing a conversation in the other room. However, set the volume too high and the sounds start to crackle.
Though the design is simple it looks a bit dated. With the heptagon shape, very sharp edges, large grey buttons, and only available in white and black may limit where you want to put this. But, at the same time, it is really a type of device that is meant to be heard and not necessarily seen. Also, the power that the LectroFan uses is standard USB 0.5 amp, 1watt. So, if you happen to be short on plugs, or forgot an adapter, any powered USB port will essentially work. So, use that one outlet for your laptop and plug the LectoFan into the computer and drown out those distracting random sounds.
