Like many others I enjoy a dripper as such I also enjoyed squonking. Yet with putting the bottles in and out the process was messy and a hastle even when you took into account the flasks to fill through the squonk 510 are a hastle. The Topside dual is an innovation allowing easy fill much the same as a tank and power almost as fast as you can hit the button. Well worth the money yet if you dont have one already consider the dual carbon with the yihi chip then you will have the topside goodness with a chip equal if not better than a DNA chipset.
