I received the product and was disappointed when I opened the box.  The contents were oily and smelled horrible and the plastic form that holds the components is flimsy causing all the parts to be strewn throughout the box when the package was received.
I tried using the tool, but the gears are coarse and not easily adjusted and I the oils from the tool left a terrible smell on my hands that did not easily wash away.
Cheap price, but cheap tool.
