This is my first try with a dual coil and I'm impressed. Previously I've used "normal" clearomisers, which I find OK but do find them a little hard to draw on at times and occasionally suffer with the dreaded "burnt" taste. These give a lovely clean vape, great vapour and I've had no burnt taste yet. The only draw-back I find is that they do use up a lot of juice and I'm refilling much more frequently, but I would say this is a small sacrifice to pay for a great vape.
