Top complaints
Tommee Tippee Multiwarm Bottle & Food Warmer
- Slow and hard to predict
Wirecutter timed 5.5 to 9 minutes and once saw a 4-ounce bottle take longer than an 8-ounce one; it has no countdown. BabyGearLab calls it not very fast, and Amazon's summary says some owners find it takes too long.
- Unclear icons, vague descaling
BabyGearLab needed the manual to decode the icons (especially plastic vs. glass), found no water fill line, and rated it one of the hardest to clean because descaling instructions are vague.
- Temperature and fit complaints from owners
Amazon's summary says some owners report bottles too hot, and some say it only works with Tommee Tippee bottles.
Kiinde Kozii Bottle Warmer
- Slow, and may not get warm enough
BabyGearLab calls it super slow: about 7.5 minutes to 80°F, and it never reached 98°F on the recommended settings (about 89°F average at 12 minutes). Babylist also says it takes several minutes longer than steam models.
- Involved cleaning
Wirecutter says the manual calls for a soapy-water clean every two to three days and vinegar descaling every two months, and a staffer noted it can't be taken apart to scrub. BabyGearLab says it calls for a bleach-and-water soak and special brushes.
- Can still overheat; uneven with frozen pouches
Wirecutter says it is still possible to overheat milk if the time is miscalculated, and frozen pouches heated unevenly (some parts over 120°F while others stayed frozen). BabyGearLab saw one reading of about 105°F on the maker's settings, above the 104°F point it uses for nutrient loss.
