Bought, not least because of the many positive reviews me this trimmer. But in short, the whole thing was a complete disappointment. Although I have no excessively strong eyebrows, the device from the beginning was so overwhelmed when it got to take more than a few single hairs at once. So always use very carefully, not too much at once. Then, after a few times using the device was getting slower - new battery, clean the contacts - nothing helped except during use at a certain point to press from the outside on the little windy housing. Have therefore decided that it is worth the effort to me not to send the device in for repair or replacement, and instead disposed to where it belongs - on electronic waste. Unfortunately, even the company Remington my second unit in the field of hair and beard trimmer so that nothing is worth. To trim eyebrows, I use since then a pair of scissors along with the small Plastikkämmchen that came with the cosmetic Pen Trimmer. After all, a certain residual benefits.
