I'm so glad I got this clipper kit. I've been using it for at least 8 months and it paid for itself by the end of the second month.I use it on myself. I just bend over the bathtub and clip away, using the clipper guide I need for the length I want. The cut hair drops into the tub and is easy to clean up with a damp paper towel.No more shaggy head for me!
