Not bad. Home appliances like this will go through their strict examination, and basically there will be no problems. However, the product is mass-produced after all. A batch of products will inevitably have several quality problems. It depends on luck. But even if the product has quality problems, you can call their customer service number and someone will take care of it. I am a senior member of Huimai. I have bought there for several years, and it is generally good.
