For a better experience, you can dilute regular liquid with water in a 1:3 ratio. It saves 50% of foam. However, it's important to note that liquids that are too thick or contain particles cannot be used in the dispenser. * 4 Adjustable Foam Modes & 45° Tilt: Press the top light to quickly switch between modes (0.5s / 1s / 1.5s / 2s mode). There's no dripping and no wasted foam. You can obtain different amounts of foam depending on the usage conditions, saving 50% of foam. The soap dispenser nozzle is designed with a 45° tilt angle, fitting naturally, preventing foam buildup, and not easily sticking to the wall. * Wide Application & Waterproof & Kid-Friendly: The automatic soap dispenser uses IPX4 waterproof and leak-proof technology, making it suitable for kitchens, bathrooms, offices, schools, hospitals, bathrooms, or countertops. The self-induction foam design and the fun of creating foam affinity plates encourage children to wash their hands.
