Are they real 510's?
My 510s are not real, they are made out of cellophane and tinfoil.
Just curious though, whats that mean "real" 510? I hear that a lot, just never really paid attention or didn't sink in.
Are they somehow superior?
And on the long lasting atty thing, my 510s last way longer, even though I'm usually on a 901....which I seem to go
through with a quickness.
