I love these bottles ! They keep things cold longer then the 24 hours . Not sure of hot manly use for cold . Any I had hot drank in the first 3hours

Keeps my drink cold, fits in my cup holders in my car, lid is perfect, and you can’t beat the price!

Nice size and quality. The lid stays sealed and I like the ease of use. Since I don’t care for straws, this is a winner.

Bottle does stay cold. I broke the push button in first month on pink bottle. But I can lock it when traveling with bottle.

Awesome bottle. Keeps cold even in a hot car. I like that the mouthpiece is covered when not in use. I will order more for gifts.

Bottle works well. Keeps fluid nice and cold. Price incredible for 2 bottles. Could be a tiny bit bigger capacity.

Love these water bottles!!! They keep your drinks cold all day and the ice lasts forever!!!! I have 6 different ones, I like them so much!!!!

Keeps drinks super cool! Only downside it is heavy! But keeping the drink cold out weight the weight of the bottle’n

Great Buy . Love the water bottles. Like the lid how you just press the button and it opens. Stays cold all day. Nice!

Keeps liquid cold all day. Easy to clean. Nice diameter for smaller hand. Zulu has great customer service.
