Atty Size

[grillman65]

OK, so on atty. and carto's. Is there a difference between 510, 901, 801, ect. besides the thread size.

510 and 901 attys are the same diameter, but the body tube of a 901 is longer (about as long as a carto) while the 510 is shorter. There is also a difference in these two in how they take in air: a 510 takes in air from the connector end when you take a draw, but a 901 atty has a hole in the side of the tube for air intake

801s are larger diameter than both of the above

You'll find there's a difference in the vape you get from each one, too
