It's hard to rate this product because it's great for some purposes and not for others. I bought it mainly to replace a rotary trimmer I hate because it's too weak and it can tug at nose hairs. Unfortunately, the new trimmer gets my lowest rating for that very function. While it does not tug at all, the blades don't even come near some of the very nose hairs I want to trim. Further, the instructions warn me not to insert the trimmer deeply enough to get at them and I can't reorient the blades to get at them. I won't be tossing out my old rotary because at least it does reach them. The good news is that I'm delighted with the eyebrow trimmer and the sideburn trimmer. Both function superbly. One minor gripe is that it's hard to see the little black on black arrows that help you orient the heads to re-attach them, but I'm getting better at it. More positives are its very powerful motor, the ease of turning it on and off, its washability, and the carrying case. If all my nose hairs grew out vertically from their roots and only from within 1/4" or 3/8" of the opening of my nostrils, I'm sure these blades would do a fine job with them - but they don't so it can't.
