Which is faster and grabs tiniest hairs?

Can you please post how the epilators you use work as to gettig those tiniest hairs? I have been using the Emjoi gold for over a year and I like how it seems to get the root out - but from what I’m reading here, I wonder if it really is.
I don’t like the shadow I still get and I think it’s the hair growth underneath. I occasionally get an ingrown hair but seldom and it’s less and less as time passes. I’ve tried exfoliating but it doesn’t help the shadow. It does make my skin smooth and hair free, but on the upper lip I sometimes see a dark stubble and of course the shadow in places. SO, i’m hoping there is an epillator that gets those tiniest hairs - the stubble. Any suggestions? Thanks!
