At least 25 one might expect at a low-end device, but it is nothing. This is properly done, and even comes with batteries (rechargeable it lacks the option to have this issue "energy" is perfect). The machine is well in hand, the brush does not (too) bad if you do not press too hard on the skin. I primarily used on the nose (where impurities and other black dots is housed). Effectively cleaning with a little soap is satisfactory and without irritation. The only "problem" is that with a washcloth and soap just obtained the same thing ... From where the 3 stars, 5 for the price, 4 for finishing and its use, 2 for the interest. Another plus: you can hang the brush with his ring.
