Did the part very pleased now for a few years and am. It took a while until I got the hang out. But now, if I properly lead the device on the nose inner wall along, you can trim the hairs well, especially the works much better than with other devices that have such a vibrating blade, like an electric shaver. Is also great, just so that you can rinse under running water part. The durability is also top. It still works like the first day.
