The Coldest Water Tumbler with Handle and Straw Lid | 3 Lids Insulated Reusable Stainless Steel Bottle Travel Mug | Gifts for Women Him Her | Limitless Collection (36 oz, Clouds of Tie Dye)

Absolutely terrible! It has a nice pretty color, but it does not, I repeat, does not keep anything cold. Ice melts within several hours. I am so upset with myself for trusting the other reviews and spending the amount of money I did for a cup that is absolutely horrible. Simply modern beats it by far.

If you hate to drink just water and you love to add a flavor this is the cup for you. It has a filter where you add the flavor to your water and you get to pick how strong of the flavor you would like. The water stays cold all day long and the cup doesn’t sweat.

I got the 36 oz from the warehouse and am still testing this tumbler out, but good so far. Ice was still very slightly present after over 48 hours. This is is exactly what I want. The opening is like a water bottle so slightly smaller than I had hoped, but that is probably why it stays colder than the average tumblers. I have only tried out the straw lid so far as that is what I like best. Handle seems put on well and I hope it won't be a problem like a lot of others have experienced. Again, I really like I don't have to add fresh ice as often and that it is basically leak proof around the house.

Water stays cold. I tested it by filling it with ice and water on a Saturday afternoon. I checked it on Tuesday night and even though the ice was melted, the water was still ice cold.
