I am 65 years old and I remember my Dad using these when I was very young. Guess What they work today. I think they are better than Chemical ones. I gave mine to my young Engineer Niece who had to work out in the cold this winter. She would tell you the same thing. I works well to keep your hands warm and your body when used in a front coat pocket. What are you waiting for? They burn for many hours of warmth with each refill.
If your nails are kept at a standard length (e.g. as in medical providers requirements), this is an excellent product. Initially when my nails had grown out too long, I clipped them. Since then, I use this to easily keep my nails at the length I want them to be (both sides--trim and file). It takes little time. Also, it is great to "smooth out any rough edges that might happen" within a matter of seconds.
