I had 2 crack on my neither in that spot. I've been holding off on sending my 2nd back because it's not effecting the performance as of yet. I emailed Brian(vaping ninja) pics of the latest one he told me a new chassis should be coming out soon and would let us know on ECF when it becomes available in the US. If you contact Vapage I'm sure they'll help you out just sucks waiting a month for a replacement.
