Review (5/5): PERFECT - AND REALLLY SHARP - BEWARE!
I was skeptical at first when I bought this because it wasn't a brand I recognized. I'm still not sure if it's actually branded either. BUT it works and it's way sharper than the branded professional one I have.
If you aren't careful you CAN shave your feet raw FAST and without realizing it until the later.
If you're used to a different file then go very light the first time you use this one to get the feel for it. And if it seems like it's taking off more than usual - don't assume "well I guess I needed it" assume "holy crap I should go lighter before I draw blood"
