It’s purple, and shiny and soo good looking 
I’ve never vaped over 120w so 400w is way overkill for me. Also, yeah they seem very hard to find. I did a quick search yesterday and couldn’t find any in stock anywhere. No purple ones anyway. As you said, they are very expensive too…but that purple loveliness! I need one!
Of course I’ll likely never get one due to the silly high price but one can dream right? 
It will sit at the top of my wish list until I win the lottery or something then that big purple box of loveliness will be mine muahahah!
