Ordered the K5 black Tobbeco from Eciggity on Monday, got it Thursday. I don't own many clones, but I'm IMPRESSED with the machining on this. Very clean, nice threading. Took the top fill cap off the clone, screwed onto my original K5, better then the original top cap, smoother! I won't know about leaking and orings till I build on it. Hopefully they used real peek insulators, don't know how to check that. Looks clean enough to Vape, but I always run new stuff through the ultrasonic cleaner. The black finish, only time will tell, just thought at this price point, would be cool to have something other then silver.
Once I buy an original and support their R & D, I don't mind getting a clone as a backup.
