The Senso-Matic chrome soap dispenser, with its motion sensor for automatic soap dispensing, is ideal for the bathroom, shower, and toilet. Simply hold your hand under the dispenser, and it will automatically dispense the perfect amount of soap. The dispenser is drip-free, easy to clean, and its 650 ml reservoir is easy to refill. A viewing window allows you to check the remaining soap level. It is powered by standard 1.5V AA batteries (not included). The infrared soap dispenser comes with a 5-year manufacturer's warranty. Screws and wall plugs, as well as adhesive pads on both sides, are included for drilling-free installation. Please note that there must be a minimum distance of 20-30 cm between the bottom of the dispenser and the sink or any other object. Set the slide switch on the right side of the dispenser to the "on" position. Press the soap dispenser button several times after filling it with liquid to allow any air to escape.
