When i first started using the Aspire x30 i thought the flavour production was fantastic. I also really liked the look & can not fault the build quality (aspire really do make their products properly!) The mod albeit looks & performs great, had quite harsh edges that meant trouser pockets take a fair beating (i have to wear a suit for work) this is obviously a personal problem but one worth mentioning. My main concern & primary reason for reviewing is to warn potential buyers of the drip tip heat! If like me you prefer long mtl draws ranging 3-5 secs ('low n slow' mouth to lung) to maximise the flavour anything over 2-2.5 secs had the drip tip heating up to umbearable temps... Real shame as the nautilus x coils gave fantastic flavour in my opinion but with no options for changing the tip this was a deal breaker for me & i had to downsize slightly to the nautilus 2 tank. If you just in it for the short drags then this tank is a peach.
