Thank you for your feedback, sir! To be honest, there is no Cordless tool that can continue working without sufficient battery. Our after-sales personnel also contacted you during the initial feedback, asking you to show the battery level. But you refused and didn't show the battery indicator light in the video. Then you continued to complain that our motor would emit smoke, but when the motor is running, the generated heat in an environment below 0 ℃ is normal to have this "smoke", just like you took a breath in winter. You may have realized a bit, so you didn't write down the reason for this negative review in the comment. But what's amazing is that in the video where you use the machine to display 'smoke' later, the machine seems to be 'resurrected' and can work normally under such pressure. This is the entire fact. We will handle any issues of our products and welcome many strict and professional customers, but we can do nothing for malicious person. Anyway, thank you!
