Only issue with them is if you have a tendency to overdrip. Mine is setup on a squonker with the bf pin so I don't have that issue but because of the placement of the airholes you could run into issues.Thanks! Just had a quick look online. They seem ok.
Yes, overall, I'm a single coil guy. Been looking for a single coil RDA for some time.
Flavour is fantastic for them as is the price point for a genuine. Can only highly recommend it, been using mine for a month now and am very happy with it.
