Ingenious modern engineering reinvents the soap dispenser with touch-free technology and clog-proof tubing. Best of all it is fully rechargeable, requiring no batteries. By moving your hand closer or farther from the spout, you can control the amount of hand or dish soap dispensed. The flexible silicone valve opens and shuts quickly for a fast, steady flow without messy drips. Powered by an eco-friendly rechargeable lithium battery, the high-efficiency pump dispenses soap in just 0.2 seconds.
