Hello @felixo and Others! 
Roughly 40 euros, but cheaper on sale. In my opinion, the packaging isn’t important, functionality matters. 
Many other things also arrive only in a cardboard box, just like the Stubby rdta tank, even though that one is 60 euros.
Dead simple, just like the other rdtas. 
Maybe you feel it hotter because of the tighter airflow, but the heat is also noticeable with Stubby rdtas and Tita rdtas if you give it less air while running the same coil at the same power output.
Some people drilled the airflow insert to allow more air through. 
The same thing happens with the Stubby closed front panel if you use a standard boro rba. There, the airflow slot on the front panel doesn’t align with the airflow slot at the bottom of the boro tank, so it gets slightly less air than a Stubby with an open front panel.
Totally agree with the end of your comment, my question for you in the end… after several days of use and testing, how do you like the Droid? Do you regret it?
