This is a great little RDA. I'm mostly into the flavour, but still vape direct lung, and the Mongrel is great for this. I use the glass cap and turn the airflow down to 1/3, which seems to be the perfect balance for me. The service fom Vaping101 was great as usual, but seeing as I'm from EU, I won't be ordering from here anymore, if I can avoid it, it's simply too expensive with customs and all. Too bad, but obviously Vaping101 is not to blame for that.
