Amazon has just put its Smart Soap Dispenser on sale for $34.99, which is 36% off its regular price of $54.99. This is the new lowest price that it has ever been. The soap dispenser, which uses any standard liquid soap, has an LED countdown on top that tells you when 20 seconds have passed, which is the CDC’s recommended hand washing time. It also adjusts how much soap is dispensed depending on how far away your hand is from the nozzle, with more soap being dispensed the lower you position your hand. The real smarts come when you pair it with an Echo device. This allows it to launch an Alexa Routine whenever the dispenser is used, which opens it up to an endless number of possible uses.
