I've used other brands of trimmers, but the Conair has the best performance. It allows one to reach deeply into the nasal passage, while the other trimmers could not reach that deeply. The only negative is that it tickles my nose, perhaps because of vibration, but I have gotten use to this characteristic.
I can truly say that I am very impressed with nose hair trimmer. It operates great and does the job better than any other I've had. And I'm 70 years old so I've had a few!
