I'm an avid Aromamizer user so I'm always going to be biased. In 1 word, amazing! Building on it is so easy. Only point is for best results, you need to mount them vertical and remove each coil to wick it. But the flavour from Nickel coils is incredible. The airflow band doesn't bother me as I always run it fully open. Would definitely recommend.
I've bit the bullet and brought a Griffin, just need to wait for slow tech. Looks epic, first builds got to be a nickel clapton.
