I'm getting ready to place an order from FreedomSmokeUSA and want to buy a few 510 attys while I'm at it. Are all 510's the same? I ordered my first attys from AltSmoke and it's called the Yeti 510. The one from FSUSA is for the Joye 510. They look the same from the pictures and cost. Are they the same atty? I'm vaping with a Silver Bullet mod by the way.
