Pro 1 joye 510 ?

[Fud]

Does anyone know what makes it a pro or a better improved model as the name implies? I was thinking of ordering a starter kit from here PRO 1 Joyetech 510 - JOYE 510 Electronic Cigarettes TheVaporPro JOYE 510 PRO 1 .

Seems like a good price but they don't specify what the difference is or if it's a knockoff or even compatible with the original 510.

Figured I would get another starter kit in stainless steel color so I don't keep mixing up flavors and as a backup. So does anyone know if the Pro is different, better, same, or just a knockoff?

PS does anyone know where to get the blue filler as well, haven't found what it is or where to get it yet after reading here for quite a while.

Maybe they're just branding it Pro to tie in with their companies name? Looks like a standard 510 to me.

The blue Fluval foam? I found it at Petco in the aquarium section.
