Customers love the tumbler’s quality and appreciate its temperature control features, with the ability to set desired temperature via the app. However, the temperature retention receives mixed feedback – while some say it keeps coffee warm, others report it struggles to maintain heat. Moreover, the durability and reliability are concerning, with multiple customers reporting it stops working and breaking after 4 months of use. Additionally, the battery life is poor, lasting only a couple of hours per charge, and customers find the value for money disappointing. The design also receives mixed reviews, with some finding it nice while others criticize the engineering.
