[4 adjustable levels foaming and no touch soap dispenser]: equipped with a high-precision sensor, the automatic soap dispenser can be foamed and dispensed in 0.3s (0.8s / 1.5s / 2s) by simply placing your hand under the sensor area (0-70 mm). No touch design: you do not need to press to avoid cross infection. [430 ml large capacity]: designed with a transparent container so you can easily see whether soap needs to be refilled. Due to the large capacity, you do not have to refill the liquid soap as often, but you can do it comfortably from above. Please note that you should add liquid soap in time if the liquid level is low, otherwise the soap dispenser will not splatter.
