I am not sure about their 24 hour claim as i drink it all before that amount of time passes mine will keep ice for 6 to 8 hours depending how warm the air is around it but no where near the 24 hours i have seen some reviews state

All in all i would have given it more stars if it would not have had that nasty plastic taste when i first tried it and having to wait for it to air out and the bottle would not get cold to the touch and the cap would thread down on the outside

We filled it with water and rolled it around on the floor left it on its side then upside down for two hours

I only have one more test to do if i can replace their straw in case it gets grungy with a thick generic straw
