Mind you as the kit comes with a rba (Mini came with a TF-CLP2 Clapton installed, a TF-T3 [Triple coil] and a Clapton rebuildable with a Clapton coil installed as well) they should be easier to build on than say the Kanger rba - whole kit was only £26.99 +£3.99 shipping less £2.70 discount.Picked one up off the counter in a B&M, last week "What the hells that"
You're right they are massive.
Waiting for FT to ship the TF-N2 Air (Nickel) coils and will have to see how they perform, but this is definitely a good contender for the Subby and Crown users.
