I loved the device at first, but now I am scared to use it. I had an Atlantis 2 on it, and at first, it consistently read the ohms as .39. Then it started jumping all over the place from puff to puff. It went anywhere from .39 to 1.2, always different with each puff. So I put my kanger Subtank nano on it, at 24 watts. It read anywhere from .55 to 1.5. Then, on the last puff before I shut the device off, it read 2.62 and burned my throat really bad at 24 watts. Since it reads different with each puff, and I don't get the new reading until after I've hit the button, I cannot check what it will be before I've inhaled. I've been vaping for years, and never felt anything like this. My chest hurts, and my throat feels very sore. Contacting the vendor now, but I don't know that I would even want to use one ever again. This was scary for me. The device had the updated chip, and was not even used for more than a half a charge. (The two tanks are fine on my other mods.)
