In the 2014 evaluation of the Hong Kong Consumer Council, the German Pool CKY-888 received an overall recommendation of four and a half stars (out of five stars), which is on par with the Philips HD9220. The German Pool Air Fryer is known as a "halogen oven" when it is sold in Hong Kong, because its body is transparent glass, and the inside of the pot can be seen to be bright and dark when cooking, and the food becomes cooked, which is easy to give people the illusion that "light is heating food". In fact, the light is generated by the heating element, when the temperature in the pot has not reached the set temperature, the heating element continues to heat and emits bright light, when the temperature reaches the standard, the heating element is temporarily heated, and the bright light becomes darker.
 
In addition to Philips, only German Pool's products are sold at more than 1,000 yuan, and if there is no strong brand appeal and active and effective publicity strategy, it is difficult for air fryers above 1,000 yuan to attract the attention of domestic consumers. The appearance of the German Pool air fryer is similar to Tefal's agitator products, the overall appearance is simple and chic, with a clamshell design, the top cover is equipped with a fan and heating pipe, but there is no rotating shaft and stirring paddle in the pot, and the ingredients need to be manually stirred or flipped when cooking. For daily home use, the CKY-298, priced at about 1300 yuan, can meet the needs, and there is no need to pursue a higher configuration of the CKY-888.
 
The biggest selling point of the German Pool air fryer is the large capacity and long timing time, both are indispensable, the capacity of up to 17L does not match the timer time of 120min, there will be two situations when cooking: one is that the large-capacity ingredients must be set for many times before they can be cooked, which violates the original intention of the air fryer to operate easily and worry-free; The other is that users can only use 1/3 of the capacity, and the remaining space will also share the heat of the heating pipe, resulting in a reduction in heating efficiency and ultimately affecting the cooking effect.
 
The temperature range of German Pool air fryers is generally 50-250°C, which is higher than most products on the market, which is one of the reasons for the large number of preset menus for its products. Of course, the maximum temperature of 250 °C with 120 minutes of heating time also means a certain risk, food heating temperature above 120 °C will produce acrylamide suspected carcinogens, the more brown the food, the higher the content of this substance. Therefore, consumers should pay attention to controlling the cooking temperature and time when using air fryers to ensure that the food is cooked.
