Does the top cap get hot?
I loved my avo 24, flavour was excellent the only real con was the top cap would get so hot it would burn my lips.
So i flogged it.
It does seem to get hot BUT the risk of burning your lips is mostly mitigated by the drip tip which stays reasonably cool. I don't foresee it being a problem for me but maybe if you had a bigger build running at higher wattage it could be. Although the post holes are big it doesn't seem there is loads of space between where your coils would sit for optimal airflow and the inside of the top cap. That said 3mm id fused Clapton fit with room to spare.
