I love them, love the colors ( I bought the black and gray). Great material! The cold water last long time.

While I love the design and size of this tumbler, I am very disappointed in how fast the ice melts. With cold water and ice, it still melted in less than 2 hours. I've tried multiple times and it still melts.

Great cups! Keeps drinks cold all day, comes with 2 different sizes of straws, protective rubber bottom, and you can choose to use the straw or to drink directly from the cup. We were so pleased with these cups, bought 2 sets of them!

The ice will stay till the next day and they do fit into any cup holder in any vehicles but was expecting them to be a little bit smaller Easier to manage while you are driving.

These are absolutely amazing for taking to my kids sporting events, Disneyland or even just using around the house. They keep my drink cold and my husband and I absolutely love them!

I fill it up with cube ice and it lasts for three days. I fill it up with cool water three times a day with the same ice I put in on day one. By day three the ice finally melts.

Love these cups! I am big water drinker & this keeps me on track. Keeps drinks cold even after sitting in hot car all day. It is pretty large and can be heavy when full ….only thing to be aware of.

This was a good deal. There are a lot of tumbler's out there that are more than the listed price for just one. They are very solid, the lid stays on pretty tight, and the contents stay cold for a couple of hours.

I love these cups. They actually keep my drinks cold for hours. I put ice at night around 11pm and by 6 am the ice is still whole and only has melted a little. Typically melts significantly by about 5pm. They are too heavy so easy to knock over.

These are amazing. Keep my drink cold for hours. I keep one in my car for water that i take to work. The 2nd one stays home for my electrolytes drink.
