No moor then one gallon!
You can fill 8oz . No problem. Can fill up to 128 oz. Your good . HARD LINE IS YOU CAN NOT FILL NO MOOR THEN ONE GALLON! We fill 5 gallon refillable containers. Every 5 gallon container removes 40 - 16oz bottles from being used. We fill 6- 5 gallon containers every 7 days. Just for drinking. Guess we are going back to 16oz. That is 240 that we will put in to a land fill . It is cheaper to buy the 240 - 16oz bottles then to pay to fill 6 - 5 gallon bottles. App Is grate if you are filling a sippy cup out and about . Not much moor then that . App is not a real world application
