Customers are saying

Customers are impressed with the Classic 25-Oz. Thermoflask's ability to maintain temperature, keeping drinks cold for extended periods and also keeping hot drinks warm. Its ease of use, including filling and cleaning, is another frequently praised aspect. The insulation is effective in keeping beverages at their desired temperature. No significant drawbacks were reported by customers.

    Great for keeping coffee hot or ice water cold. Easy to clean. The wide top makes it easy to pour in hot coffee or add ice cubes.

    I have a smaller Stanley cup and love it. Best Buy had a sale on this one and I knew I had to try it. This keeps my water cold all day and does not leave a metal taste at all. My husband uses his for coffee and it keeps his coffee hot all day and after it is cleaned there is not lingering smell.
