Not sure what to do with this ?

First it came with no directions. Second, I used the nose hair attachment in my nose & it smelled like burned hair...it worked ok but scary & not sure it was supposed to smell like that. Third, I have no idea how to use the eyebrow attachment . The plastic cover doesn't seem to come off but I DN understand how it works with the cover on ??? I shaved the hair off my arm with the one attachment & it seemed ok. I'm a 64 year old woman, not a man btw. I have a few more days to work out these issues before I need to return it. I suppose the answers I get, if in time, will determine what I'll do.
