Query: WORTHLESS

I have a lot of experience with male grooming devices. I am a fairly hairy guy with a mildly hairy back. This thing could not cut one single hair from my back no matter what angle I tried. I am not sasquatch. I returned it and tried a second one just in case it was defective. I could not cut a single square inch on my back. It simply would not cut hair at all. A total piece of junk. Not sure how anyone could possibly have gotten any use of this thing unless I have alien hair. Avoid at all cost and furthermore extremely cheaply made.
