I have or have had many rebuildable atomizers but prefer drippers, and there are now tons with Nimbus and Nimbus clones, Tridents and Trident clones, even Immortalizer and Immortalizer clones, but I find myself reaching for my IGO-W most often. That's why I don't understand why it's been getting a bit of a black eye in some of the reviews and articles I have been reading, here is a good fairly unbiased IGO-W article if interested, I mean for the price of what, $18.00, often less on sale I don't think it can be beat. I think the size and shape are perfect, there is plenty of room to build coils, and I really like the minimalist looks of it. Does anyone else agree?
