The nose/ear trimmer was good to use in / on my ears however after I used it in my nose I noticed an irritation and some soreness.. I had inadvertently cut the inside of my nose in two places. 2 very small nicks but quite painful. Next time I use it in my nose I will have to be more careful. If I get the same problem again then I will write another review. I have used one before without any nicking but quite painful hair plucking.
