Weedity is right. Using the E-hookah e-cigs, you won't get that much vapor or flavor. The e-cigs they sell are just regular cig-a-likes, which in my opinion, don't make much vapor, and little ego batteries (and most don't have variable voltage). The ego batteries aren't too shabby, but you can buy a nice ego c-twist or vision spinner anywhere, get a nice tank, and get much more vapor than with the kits Starbuzz, White Rhino, and Fantasia are selling.
Come to think of it, I did try the White Rhino flavors when they were set up as samples in the B&M one day (White Rhino also makes shisha) and I hated all of them. Just tasted really cheap. Nothing like their shisha. Maybe Starbuzz and Fantasia do a better job. I also had a Starbuzz disposable cig-a-like (the blueberry one) and it kinda tasted like the shisha. Wasn't too terrible.
In my experience, e-cig flavors are similar to hookah either way, no matter what brand you buy. Essentially you are vaping flavored vapor and hookah is just inhaling flavored smoke. E-cigs just don't have that slight smoke/charcoal taste. If you get a nice e-cig setup, you can blow just as big of clouds as with hookah. If you really want huge clouds, get a 100% VG liquid, a variable voltage/wattage or mech mod, and maybe even get into RBAs. You'll cloud up a whole room in minutes.

But even with just a variable voltage ego battery, a decent tank, and high VG liquid, you can still get clouds comparable to that of a hookah.
