As far as the TFV Mini...
And mostly quoting myself from another thread, but...
Single coil nazi here, been rebuilding since the 1st vape, and never used prebuilt coils, didnt become a vaper to get mired in brands of coils and consumables.
I own a Lemo 2 (used to have a Lemo 1, its passed away sadly), and a TFV4 Mini - which i got and straight away gave away all the fancy coils for it within minutes (bought it during a vape meet at my local b&m) to someone else i know who also bought the TFV4 Mini that night, and am sending the dual deck RBA, which i got as a bonus when i bought it, to someone here on the forums, as ill never use it.
Usually running 0.6ohm 3mm ss in the RCA deck on tc
Yup, single coiler...i like no muss, no fuss vapage.
The TFV4 is a step above, flavourwise, my most loved tank the Lemo 2. You dont need octocoils to get a decent vape out if it.
