It's very easy to use. Rechargeable with a USB cabel, so you dont need batteries. Very easy to use and the device's light shows the mode that was choosen so easy to set it. It has 5 different vacuum suction level and have to say that it is very powerful. As a bonus, it is not only a blackhead remover but also has LED lights to improove the skin quality. I am very happy with the product.#rankboosterreveiw
