Founded just a few years ago, Kiinde has developed a complete line of baby feeding products that make tedious steps easier and more user-friendly, and its only bottle warmer, the Kozii, has been voted the best product in both The Wire Cutter and BabyGear Lab reviews, and is also the best value for money bottle warmer selected by Best Reviews.
 
Kozii has been favored by so many reviews because of its unique design, which makes it the easiest to use product among brands of bottle warmers. Unlike the general bottle warmer designed according to the water temperature and function, the Kozii only has a timetable dial as a timing device, which can be set to a maximum of 15 minutes in units of half a minute. Kozii's instructions list the required heating time according to the different bottle material, milk condition, and milk volume, which can be used as a reference, as long as the time is set appropriately, the use of Kozii is not prone to overheating of milk.
 
The design of Kozii's inner chamber is also different from that of common bottle warmers, with a reservoir under the inner chamber where the bottle is placed, and when the machine is started, water enters the inner chamber from the reservoir and the milk is warmed through a flowing water bath, so that there is no uneven temperature of the milk, and the warming speed is also relatively fast, using a glass bottle to warm 120mL of milk in about 5 minutes and 30 seconds. When the time runs out, the water returns from the inner chamber to the reservoir, preventing the milk from continuing to heat. When the reservoir capacity reaches its maximum, it can warm milk 5-10 times, so there is no need to add water every time it warms the milk.
 
Due to this design of the inner chamber and water reservoir, the Kozii cannot be used without a bottle in the inner chamber, and the machine must be turned off before removing the bottle. The concealed cistern also makes the machine very cumbersome to clean, and it needs to be cleaned every 2-3 days of use, and it needs to be thoroughly soaked every 2 weeks.
 
In addition, the Kozii is compact and compact, so it does not take up space on the bedside table, but the inner compartment can accommodate a comotomo bottle of equal width, which is highly adaptable. At present, Kozii is not available in the official e-commerce flagship store, and can be purchased through Amazon Overseas Purchase, with a price of about 380 yuan.
