I'm happy to take suggestions - remember, the goal here is for people to be able to select the model of e-cig that they use from a menu - I'm not really trying to list what's compatible with what....
I thought the easiest way of doing that is to select 'type' then 'model' (and model is optional, so you can just say 'I use a mini' if you want).
If folks want to see the EVO on there then please list how it should appear, such as 'Mini:Evo'
(I'm not familiar with the Evo models).
