If excessive noise (or utter silence) makes it difficult for you to doze off, this feature-packed white noise machine might be the key to a better night’s sleep.

LectroFan can pump out 10 white noise sounds and 10 fan sounds, all of which are generated dynamically, without any jarring looping. Today’s $35 price tag is an all-time low, and $25 less than usual, but it’s only available today as part of an Amazon Gold Box deal.
