Eskimo Coolers Stainless Steel Double Wall Vacuum Insulated Tumbler with Lid,30 oz & 20 oz. Combo Set of 2

Really a great price and high quality. I use mine every day and have put away all my plastic glasses. My smoothies stay satisfyingly cold and they are easy to rinse and clean. Glad I grabbed these !

Your claims are greatly exaggerated. This is a nice travel cup and does a decent job of keeping liquids cool, but holds ice for 72 hours. What have your marketing people been smoking? I have followed all of your instructions to a "T", but 72 hours? Who are you kidding?As I said, it is a nice travel cup, but from what I have experienced the only thing your claims have justified is the price you charge. I, for one, did not get the value justified by your price. At half the price and half of the claims, it would be a five star purchase. Nice try.

After the first day I didn't think It was going to hold ice very long, day 2 and up till now it holds ice for a good time last night and made a drink my last drink at 10:30 and it still had ice in it till 2 p.m. in the afternoon and my drink was still cold I would do this cup again thank you.

Sorry these cup do not hold ice and water for 48 hr ! You are lucky if they do for 8 hr usually only 6hr. These are not what I expected from their false add I was VERY DISAPOINTED .

Did not work for hot coffee, kept it warm at best for about 30 minutes or so.

I like these tumbles. They keep beverages cold or hot for a very long time, even in a hot car. They stand up to their guaranteed claims.

So far excellent results. The 30 oz is maybe too big for the car, and heavy to carry when full. But the ice lasts 24+ hours, which was my goal. The lid has a opening for drinking,but it does not affect the temp, but it can spill your drink if loose.

Coolers work great, but a bit too pricey, I found the same type of cooler at a walmart website for half the price of these.
