    We used this product when our daughter was born;we used to keep hot water for making milk for her. This item was good for few months later hot items will not remain hot after some time.

  • Doesn't keep hot very long
    Verified Purchase

    Unless you are going to drink whatever you put into this thermos quickly, be prepared for it not to stay hot/cold for very long.

  • just right for the price
    Verified Purchase

    No overall complaint. It keeps my smoothies cold all day. The only issue is that one of the stainless steel cups. Sometimes when I go to unscrew it from the thermos, the stainless steel shell detaches from the plastic cup. I push back on and it may not happen again for a week or so. Just a slight nuisance. I like this product and would recommend it.

  • Keeps my tea hot throughout the day of work
    Verified Purchase

    This thermos keeps my green hot tea hot from the morning to late afternoon while at work. I make my tea at work and keep it by the desk. The size is good if you drink a lot or plan to share with others because it is a 1-liter is plenty for you and your buddies. I don't have to get up and buy a drink or having to make more, I just have it ready right there, very convenient. In the negative side. To clean it you have to have a bottle brush long enough to reach the bottom specially if you want to keep it spotless, but this is just me. I don't want to build stains, we will see.

  • Thanks other reviewers, very happy with purchase
    Verified Purchase

    Thanks to reading other reviews, I felt more confident in placing my order for this product. I was very happy when I received them (bought 2). Having the 2 cups is very handy. Nice to also have the carrying case. Great to take to work or on a road trip. They looked just like they were advertised. I’ve used them for soup and tea and it’s keep them steaming and nearly boiling hot for over 5 hours+, so be careful. Because of the length/depth I need to get special cleaning tools if I don’t want to keep using the dishwasher to clean them. Otherwise, I’m thrilled. I wish I had gotten them sooner.

  • Great Product

    Great product! Have been using daily since purchase. Make sure to buy a bottle scrubber with this as it is a large container with small opening.

  • Great Product
    Verified Purchase

    My wife bought one of these at a garage sale and fell in love with how this product worked. It kept the cold water extremely cold for very long periods of time and vice versa for hot tea, etc. So, when hers broke, she was desperate for a replacement. I checked online and purchased this item from Overstock and it is great. It was a bit improved on the design and even came with a carrying case and an extra cover for the product. I was shocked to see how low the price was as well.
