Title: Expensive, not worth the price!
Review: I am not sure where others have used these tumblers. I have the small and large sizes, went for the straws and lids, handles, bought it all hook, line, and sinker (stinker) from their website reviews. I have found that they do not keep drinks hot or cold very long at room temperature with AC. I have filled with ice and taken to work for a few hours and it is water. The hot drinks stay hot for maybe a half hour. The only good think is that they don't sweat on your desk or table. But that is a high price to pay when you could just use a coaster. I don't see how they claim to use these in a trunk in Arizona with ice for a day nor in Alaska for 4 hours for a hot drink. I am in Pennsylvania indoors and they don't work for me. I am very sorry I purchased many of these for Christmas gifts last year, I will never do it again. I embarrassed I purchased such low quality gifts.
