It produces one continuous sound so your sleep won’t be disturbed by looping. LectroFan is a good alternative to the high cost of over-the-counter sleep aides or prescriptions without the potentially dangerous side effects sleep medications may cause. 20 Unique Digital Sounds Since there are no memory restrictions, the LecroFan can provide 20 different sound options. It has two ways of eliminating unwanted sounds: 10 non-repeating fan sounds and 10 non-repeating white noises. Simple, Compact Design The LectroFan was designed with simplicity in mind, so you can spend less time fiddling and more time sleeping. Use it in your office, or bedroom, or take it with you on your travels. The versatile LectroFan uses a USB cord so it can be plugged into the supplied AC adaptor, computers, or rechargeable battery packs. It`s easy to use, no matter where you are. Precise Volume Control Multi-level volume control allows you to adjust to any environment. Smooth 1dB increments give you complete control from ten times quieter to ten times louder than traditional fan-based machines.
