My wife surprised me with one yesterday and so far, its the best RDA I've ever owned. My only gripe is the whistling. I've tried wicking it a couple different ways using more / less cotton and adjusted my coils but its still there. Is this a common issue with the Petri's? I think its related to the air holes, of which I can do nothing about. However, if there is some kind of way to stop or even quite it down a little I'd love to hear it.
Thanks
