I wish this in my life sooner. I have a good eye for balance but this would have been a great tool for trimming out the various shapes. I have used it on myself and was very pleased with the results. I feel like it’s the first time in a while that everything was balanced, and that’s not always easy to do freehand on yourself. With the pencil, it’s easy to draw your shape. I would recommend trimming any hair that will be above the shaper tool so you can get a clean line with the pencil.
