Hello dear, we introduced our product parameters and working videos to you in detail in the early product communication. You paid the order after confirmation. Before delivery, we also shared the inspection video and pictures with you for your confirmation. We delivered the goods only after everything is correct. After you received the goods, we can see through the video that the machine is working normally. If there is any after-sales problem with the product, we will solve it for you. But the machine is working normally, so there is no need to replace it. Regarding the energy you mentioned, we can use an energy meter to test it. I hope you can understand. thanks.

Dear, thank you for your recognition. If you have any further questions, please feel free to contact me and I will provide you with services
