Received The V3 form fasttech and I love it! Very well made...SOLID and vapes great for me @ 10 watts =) One thing I love is that when using a tank [Im carto tank all the way] I can unscrew the top cap of the V3 gently till it hits the bottom of my tank to control air flow and it make the draw quiet... GREAT VAPE! I use 2.0 ohm smoketech prepunched cartos with a pyrex sidewinder tank or pyrex 505 tank... Love both of em! Vapin some Ikenvape RY4 gold right now... Yummm mmm
