Klean Kanteen Rise 10oz Lowball - Stainless Steel Tumbler with Flip Lid - Stellar

The Klean Kanteen Rise 10oz Lowball tumbler has garnered mixed reviews from customers, reflecting a blend of admiration for its design and heating/cooling capabilities, alongside notable criticisms regarding its functionality. On one hand, users appreciate the compact size, which encourages them to drink more frequently by forcing them to refill it rather than lounging at their desks. The tumbler is praised for its ability to keep drinks at the desired temperature for an extended period, particularly excelling in keeping cold beverages cool. Many users enjoy its aesthetic appeal and rugged Construction, stating that it has withstood drops without damage and is visually appealing enough to gift to others. However, significant concerns have been raised about the lid's design. Some customers report that the lid is not entirely leak-proof, and liquid can spill easily if the cup is tipped. There are also comments on the lid's fit, with several users experiencing issues where it doesn't seal securely without careful pressure application. This has led to frustrations, as some found themselves unable to fully rely on it as a travel mug or for use outside of controlled environments. The claim that it does not retain temperature as advertised has also been a disappointment for customers who anticipated its performance based on previous experiences with the brand. In summary, while the Klean Kanteen Rise tumbler offers a delightful combination of style and thermal performance for appropriate scenarios, it has not fully satisfied all users due to its lid's design flaws and inherent usability concerns. **
