The Vapor Giant V4 has been a staple favourite of mine along with my Skylines and the V4 went on my European trip with me. Now they have just released the V5 and I jumped at it... and it's just what I had hoped for... more air and more juice flow... straight away I can say chicken dinner after building it... I popped in a 3mm Fused Clapton from @RiaanRed and it came out at 0.51Ω and then I put it on a Hellfire Phantom because it's 23mm. The airflow is really smooth and open and the flavour is on point!
