While the build quality of the unit is good it is absolutely, totally, and completely inadequate to the task of removing whiskers from a 24 hour old beard. Tried the very poor Derby blades that came with it to no avail. Tried my trusty old Personna Blue labels to no avail. Finally put in a Feather and still could not remove the stubble from my face. I have an average beard and not sensitive skin. I have no trouble with my Lord 626, L5, Gillette Tech, Knack, or slim twin Schick. Bottom Line:This thing could not remove the hair in three or four passes. There is just not enough blade exposure. Do not be fooled-While it looks like a copy of a Gillette Super Speed it is not!
