What about the high-value sea? Is it practical or just beautiful? Tell me about used ones.

Good cost performance. Accessories are complete, comprehensive and thoughtful, and the size is moderate. The operation is simple and the internal workmanship is "advanced". I remember baking it for 20 minutes before using it for the first time, then frying French fries and roasting chicken wings continuously, working for an hour and a half, oven! No problem, but the surface is slightly hot, and the use effect is still relatively good. French fries are very successful, and their taste is better than that of air fryer, comparable to my favorite KFC. Chicken wings are also very effective, with a yellowish surface and fresh inside. The whole use is quite surprising.
