I've tried many drippers from fasttech. Plumeveil, stillaire, doge, zenith, mephisto, magma, patriot, etc. but the igo M and igo M2 really pop flavor wise. It is easy to build on with the quad posts for single or dual coil. Price is less than 12.50 if I recall and has a 5 star rating which in not too common for drippers at fasttech. I am very happy with it. I mainly chase clouds, but when I want my flavor fix the igo M2 comes out and I build 24g or smaller single coil, close off the airholes to a minimum and voila! The cloud capability on this is not too shabby either. It has 6 monstrous air holes which can be fully adjustable. Not really sure why this igo is such a flavor beast. Maybe a more experienced user can chime in?
