I accidentally ordered this instead of the OBS so please don't make the same mistake I did. I do feel like I can give this is a decent review as I compare the OBS and the SMOK bulb. They both will achieve the same end goal but this SMOK bulb comes much more well packaged and safe for delivery of glass.
Got it next day, 2 day's later dropped it and smashed it. The world is telling me something i'm not sure what yet, possible just stay in the seated position at all times, defo not give up vaping.
