The Target seems to use coils that run ~ $3.00 USD, a piece. Imho, that would be a dealbreaker. If Vapresso comes up with an RBA assembly for your coils, that would rock! I realize, too, they're using mesh.
Have not used it, so cannot offer opinion on good / bad either way. Likely that mesh coils do not facilitate an RBA style deck assembly. In any case, to me, anything over ~$1.50 USD for a coil assembly seems, too expensive. You may go broke trying to keep coils stocked.
Please note, these are simply my opinions based upon speculation of the product. Not disparaging the Target kit, Vapresso, or anyone choosing to use that product. Merely expressing some thought on purchasing, as it was asked by the OP.
Apologies for qualifying, seems I must, though.
