This is a great tool! Especially this time of year! I have course dark hair. The picture is side by side of my legs with one a week or more of growth and the other just used this!
I bought this for a cruise (have not used it yet). I love that it folds up and hides in its little case and I can clip that case to my belt loop or something and always have it on hand. Haven’t used it so not sure if it will have a residual taste like rubber things tend to or not.
