I just got my 510 in from Healthcabin and they are "genuine". They are a little different from the Widows 510's though.
1) The carts are a cigar tip type (like a 901). They also fit tigher on the unit.My "old" carts also fit on this one more snug like my Janty atomizers.
2) The button pertrudes out from the unit a little more.Not a big deal but it feels a little more "substantial". havent had any trouble with the Widow ones though.
3) The titanium is cool!
