I've tried another Flying Eagle blade and it was terrible. I couldn't make it through the shave and binned it somewhere about half way through the first pass. It wasn't sharp enough to actually cut through the hair but just sharp enough that it grabbed the hair and hung on to it just enough to pull it out root and all.
The Chinese blade seem to all have a reputation of being pretty much complete garbage. My recommendation would be to skip this one.
I have. One was included with a $2 Chinese made TTO that I bought just for a cheap razor travel case that was included with it. The blades are the worst of the worst.
I wouldn't trust Chinese blades as far as I can throw them - That's about as far as File #13
