I like my old one better
In my uploaded pic, on the left is my old one.  My old one has visible teeth and works quite well.  It is useful for the nose but also eyebrows or anywhere.  On the right is this 'Nose and Ear Hair Trimmer'.  When using this one, the hairs need to go into the small slots (the slots are clear in some of the sellers pics).  You need to keep moving it around until the hairs enter the slots which is where the blade is.  I was due for a nose trim so I tried it out.  It took considerably longer and just did not do as good of a job.  I finished up with my old favorite.<br />In fairness, this new one is much gentler, my old one does make the inside of my nose a little raw for a brief period of time but not a big deal.<br />I am giving this 'Nose and Ear Hair Trimmer' 3-stars.  It works but just not as well as others and also is limited to nose and ear and not effective for eyebrows.  If sensitivity is your primary concern, this one is worth considering and I would recommend.  But for all others, consider the versatility and better performance of other styles.
