Simply hold your hand under the soap dispenser, and it will automatically dispense an adequate amount of soap. The dispenser does not drip, is easy to clean, and the 650 ml chamber is easy to refill. The viewing window allows you to check the remaining amount. It operates with standard batteries (1.5 V AA), which are not included. The package includes screws and plugs, as well as double-sided adhesive pads for mounting without drilling. When attaching the soap dispenser with tape, it is advisable to additionally apply silicone to the free areas on the back for better grip (not included). The mounting distance between the dispenser and the surface (e.g., sink) must be at least 20-30 cm. Before use, ensure that the device is turned on using the switch on the right side. After filling the liquid, the soap dispenser should be activated several times to allow air to escape.
