I received it twice in total, and I like it because other people can recognize it! I really didn't think I could do 30 minutes ㅜㅜ so I got FX for 15 minutes, but I recommend it because even without dieting, I only lost my facial features! Recommended for people who are concerned about facial fat, especially sagging, bulldog skin ㅜㅜㅜㅜㅜ
