This thing is magic!!!
Don’t buy a Yeti tumbler for $40 to keep your water cold, buy an Ozark Trail Tumblr for $9.74 from Walmart to keep your water cold FOREVER.
Seriously, this thing is awesome. I filled it with ice and water at 8am. It’s still full of ice nearly 6 hours later. I watched a video that compared them and this one still had ice in it after 56 hours. I was sold.
It also works for keeping beverages hot so perhaps this winter I’ll try it!!
