Review on Convenient Wireless Rechargeable Auto Bottled Water Pump with Volume Control - Dispense Water Easily from Gallon Bottles by Gary Cole

I work jobs where we order 5 gallon water jugs and used to rent or buy dispensers which were always difficult to order, clean and repair. I've seen this and it's just as good (if you're just fine with cold water/room temperature). Battery life is typically 2 jugs for me, but I try to charge each switch overnight. I wish you could use the pump/buttons when they were plugged in so you could charge and use them and unfortunately that's not an option so make sure you charge them when they're not needed. It's easy to put together and easy to take apart for me when we're out and easy to clean too. There are several types but I like this one where you can choose the size and it automatically spreads out to that crowd, very neat!
