You need this to get your water in
I'd say i got a pretty great deal on this one. My package got lost for a month and amazon returned my money. Ones sure it wouldn't show up. But one day it did. I wish it had an option not beep at me instead of just lighting up. But it works fine and I remember to drink my water. My hold frail water bottle would be stainless steel with time or oz markers. I like my water nice cold so the plastic bottles just don't do what I need them to do. This thing is great on my 40oz tumbler.
