The product works fabulously. The rasp might be something fine but that's not really a criticism. Handling (best for dry skin) is a breeze, the result is absolutely convincing. The result is a lot of skin dust so you should grate on the tub, outdoor or at least over a large surface and polish. When reasonably careful handling is no risk of injury, the ergonomics of the product is excellent. Keep to a well thought-brand product that is worth its price, in my hand.
