I recently bought the Aspire Nautilus and love it. It has a new type wick that lasts forever and with the watts turned up to 15 it vapes like a champ. The wick is like nothing I've seen before, It screws into the bottom of the Nautilus and after filling it with e-juice you screw the bottom back on as it screws itself into the top at the same time. I've never seen a wick like this but it works great.
