hi all brand new to the forum and vaping. Decided to go for the aspire premium kit with the nautilus tank. I've received it today and when I screw the tank into the battery, if I screw it any further than 3 turns the unit flashes 3 times and won't work. But it will work if I leave it loose (about 2 1/2 turns) but then it shakes around and looks unsightly with about a 3-4mm gap visible between the battery and tank. Is this normal or should I send it back? The company are being helpful and are willing to take the unit back but before I go to the trouble and cost of mailing it back I wanted to make sure this is not normal. Any input would be greatly appreciated guys. And also where do people get the the best flavours on the web? And what are your fruitiest favourites? So many to choose from! Haha. Thanks again.
