I think that the first two were pretty much identical but this one actually reinvented the wheel a bit so is more desirable imo....here's a review of the original by Todd's reviews..
I hope it doesn't whistle too much otherwise I might be driven crazy also![]()
Thanks Charlie. After skimming through that quickly it seems that it has kept the NarDa's reduced chamber but the airflow has changed, it also has a much deeper well and looks simpler to build. To be honest it seems to share many features of my O-Atty V2 clone which is also very flavoursome but was limited by having a similar small well as the original NarDa. I might have to grab one from fasttech myself.
