I am extremely pleased with my purchase. The water stays cold.
The only downfall is they no longer offer flip mugs. I have arthritis in my hands and the screw top is a bit challenging but, I do love everything else about the bottles.
I love the mint color of the bottle!
It holds the perfect amount of liquid to quench my thirst on a hot day! It keeps my drink cold for hours in the summer heat! It's a fantastic bottle...My friend wants me to order him one!
