Well if you ever want to chat about VapourArt gear then just send me a message. I can talk about this stuff for hours.
I'm also curious if you've ever come across anything that vapes like a Heron 1.5. The closest I found was Titanium Mods Ukraine Prometey III. That RTA uses filler material just like you can use with the Heron's and Spheroid. Also it's gravity fed wicking too. Sadly they don't make that version anymore.
I've ordered a Flash-e-vapor clone, it seems like it may offer a similar style of vape and at the price is worth trying out.
The Kayfun Prime with the alternative air nozzles for NET tobacco almost has a similar flavour profile as the Heron with some juice, but the standard airflow which comes as default is nothing like it.
If I'd known at the time VapourArt were going to close I would have bought more Heron 1.5's. But they stopped stocking it apart from some parts and had moved on to the V2. I got my 1.5 from a listing on another vape forum.
