I purchased this coffee mug with a removable lid and automatic stirring function and I am very satisfied with it. The delivery was fast and the careful packaging kept the product in perfect condition. The design is practical and modern: simply press the button on the handle to mix the drink without spoons, making use comfortable and clean. Charging occurs via the included USB-C cable, which can be connected to the base of the handle. Only small defect: the length of the USB-C connector, once inserted, exceeds the base of the cup, so to recharge the mug you need to place it sideways and not hold it upright. Overall, it remains a useful accessory, original and of quality, ideal for coffee, tea, cappuccinos, and hot chocolate. Recommended!
