Electric razors can work well for shaving different parts of the body, including legs and underarms. They are efficient for quick and convenient shaving, but may not provide as close of a shave as traditional manual razors. Some people find electric razors gentler on the skin and less likely to cause irritation compared to manual razors, making them a popular choice for sensitive areas like underarms. Ultimately, the effectiveness of electric razors for different body parts can vary depending on individual preferences and skin sensitivity.
