As one of the symbols of German industry in the new encyclopedia, NUK not only has its pacifier and pacifier products certified by the British Dental Association, but its bottle warmers Thermo Rapid and Thermo Constant have also received excellent (sehr gut) and good (gut) evaluations respectively in the well-known German magazine TESTMAGAZIN.
 
However, the Thermo Rapid and Thermo Constant are now discontinued, and the NUK Bottle Warmer is now divided into a Chinese version of the multi-purpose bottle warmer and a European version of the Thermo Express Bottle Warmer, both of which have the same appearance and different functions. The Chinese version is priced at 209 yuan, and the three functions of thawing, warm milk, and hot complementary food each have 2 gear controls, but the machine power is only 100W, even if the high-level warm milk is selected, the warm milk speed is still not fast enough.
 
The European version only has a switch button, no gear adjustable, and the multi-functional bottle warmer uses a water bath to warm the milk, this bottle warmer is heated by steam, which is faster than the Chinese version of the bottle warmer water bath to warm the milk, and after turning on the machine for 90 seconds each time, the operation is simple, but there may be a single start The milk temperature is low, and the milk will overheat after two runs, the time is relatively difficult to grasp, and the price is about 20 pounds.
