It's a fantastic RDA, both in dripper and squonk mode. Be warned though, the well isn't very deep, so you have to practice just how much juice you can get in it before it overflows as the airflow is under the coils. The flavour off it is outstanding though and worth the odd gurgle. Another one to consider would be the Drop. That's a little more forgiving. I don't own one but many I know that have it have said the flavour is exceptionally good. I can also vouch for the Dead Rabbit. That is probably the most forgiving for over squonking and if you fancy a single coil build, the Dead Rabbit SQ is something very special, also the Advken Gorge. I'll list them for you:
Phobia - incredible flavour, be careful not to over drip/squonk
Drop - great flavour (I've been told) and more forgiving
Dead Rabbit - excellent flavour and very forgiving
Dead Rabbit SQ - great flavour again and designed primarily for squonking, but can be used as a dripper
Advken Gorge - very similar to the Wasp Nano, but bigger and better airflow. SIngle coil and fantastic flavour.
Oumier VLS - excellent flavour and very versatile deck. Dual vertical coils are my favourite
