I've been using my Pockex since November and over the past week its started to get hot when vaping, visibly burning the juice in the Pyrex tube and spitting like a navvie. I've changed the coil, well the shop I brought it from did that for me, and I left it for a good 15 minutes while the new coil was charging with juice as I wondered if that could be the problem... but its still doing it. Seeing as its now over 3 months since I brought it, and its now started doing this, the warranty is no longer valid. Has anyone got any idea's how to resolve these issues? As its getting annoying and expensive.
