I appreciate that it does for you. For me, as for as Multi-Coil RBAs go I think the Estia is hard to beat. I was speaking of the Single Coil type RBAs. I should have been more specific. I find it difficult to compare a single to a multi rba/rda.An estia blows the heron out of the water anyday.... How can 1 coil be better than 3 coils? Sorry, but not sorry
The design and functionality of the Heron and Promety works for me better than other single coil type RBAs.
