It's a great vape in the 23mm version. There is a valve to fill the tank like the Kayfun 3.1 had, but this one actually works properly and can be removed for cleaning. Velocity style deck, with a choice of single or dual airflow options. It's always a conversation piece at the local B&M with the TFV crowd.So I can give it a pass and not miss out on too much. Thank you. I think right now novelty is where I'm heading with a lot of the newer gear being released. I am intrigued by the new DNAc replay function. Seems it may benefit those of us that don't care to play with tc and curves.
When Shenray made the 32.5mm version, they just opened the 23mm version's CAD file and hit expand like they usually do... The chamber is huge, you could mount 4 Notch coils in there without much effort (15mm across the posts), except then never thought to increase the size of the cyclops air holes...

If you can get the 23mm version on clearance from the Chi-Nee then it's a fun tank to play with.
Just a little FYI, the stock drip tip has an 11mm bore, but they do include a 510 adapter.
