Review (5/5): Works great and causes zero pain!
This hair trimmer is wonderful. It works really well and cuts without pulling. Anyone who has used a nose-hair trimmer that pulls the hair while it cuts knows the exquisite pain it can cause. It is enough to bring you to tears. This works so well that the only way you know it is even cutting the hair is that the sound changes when it cuts hair. I would definitely recommend this product.
The only possible con is that it does seem to heat up in the cutting area while you are using it. It hasn't been a problem, but I thought it was worth mentioning.
