I've been wondering about these (e.g. 3Fvape) and this is the first "in the flesh" report I've seen:

Evolve DNA 40 clone temp control - first look

Good to see these aren't the DNA30-clone-upped-to-40W that some people got caught with.

Anyway, it sounds promising for those that are unlikely to pay for a real Hana, Vapor Flask or Vapor Shark DNA40 and want to try TP. Build quality looks reasonable too.
