Mainstays Mainstays Dinnerware Editorial Review
The Mainstays 20 oz Double Wall Stainless Steel Tumbler with Straw Lid has garnered a largely positive reception from users, particularly for its design and functionality. Parents with young children have praised this tumbler as the best option among numerous trials, noting its ideal size, appealing design, and effective leak-proof feature. Many report that it keeps drinks cold, maintaining ice effectively for over 12 hours, making it a favorite for various beverages, whether warm or cold. The tumbler's Construction is highlighted as a strong point, with a durable metal body and a sturdy plastic lid. Users appreciate the easy cleanup due to its dishwasher-safe design. However, feedback concerning the included straw has been mixed; while some find it practical, others criticize the suction required to drink comfortably. The straw’s assembly can also present challenges for some users, leading to suggestions to adapt it with a standard straw for better usability. Despite some drawbacks, such as the potential for carbonated drinks to build pressure and a need for stronger suction with the straw, the overall sentiment showcases the tumbler as a reliable and stylish choice for both adults and children alike. With great insulation properties and a secure lid, many users express a willingness to purchase additional tumblers, reflecting high satisfaction levels across various age groups.
