Junk Item Plus Minus Zero Auto Soap Dispenser Foam Light Gray (closer to white) Set of 3 Power turns on and there is an operating sound, but foam sometimes comes out and sometimes only air comes out. It's a set of 3, but some units dispense easily and others are difficult. The cause is unknown, but perhaps someone who can open it up and repair it themselves would be interested? Batteries are not included. Also, in terms of appearance, there are slight scratches and some rounded corners from bumping during cleaning. Size: Approximately Width 70mm x Depth 135mm x Height 198mm Requires 4 AA alkaline batteries. Please understand that this is a junk item before purchasing.
