Simple Modern bottle can’t keep water cold for 24 hours

Isn’t that what it says? If there’s a little bit of water with a drink mix in it, when I get home, it isn’t cold anymore. That isn’t even 10 hours. Maybe 3 hours or almost 3 hours.

Might work if the water is colder. My fridge makes a dying sound when I open it, or it use to, I haven’t noticed it lately. The freezer is cold, probably to cold. How does the freezer still work, but the fridge part might not?

All I care about is no water on the outside. It does that just fine. Wouldn’t of ruined my desk if I had it sooner. It’s got water stains on it. I assume that’s what it is. Repaint it. To lazy to do that.
