The rotating cutter head fits the face and head contour very well, and the hair at the corners can also be removed cleanly; The blade surface is very smooth and will not hurt the skin at all. When using it, it feels like a silk scarf wrapped around the head, which makes me feel that it is a very enjoyable process. The intelligent display screen has given me great convenience. I can know the remaining power anytime, anywhere, Most importantly, it is very durable. I have used it three times and it takes 5-10 minutes each time, but the remaining power is still 80%. Therefore, I only need to charge it once to achieve long-term cleaning, which is a very cost-effective product for me.
