I just got my tobeco clone today,and i gotta say what a pain in the *** to get the coil in these things haha.It took me almost an hour to finally get both legs into those tiny holes.After taking the first draw,i realized all the cussing and thoughts of throwing it out the window were worth the aggrivation though,as this is a really nice attie.I've gotten used to the airy draw of my orchids,so i was a bit concerned when i read that these have a fairly tight draw,but again i was surprised,it's actually a pretty good amount of airflow,definitely better than a kayfun.I had originally bought this with the thought that if i didn't like it,i could easily get double what i paid for it back,i grabbed this thing brand new for $12 with shipping included,but now after using it,it's definitely gonna stick with me haha.Now i have the aqua v2 on the way,so these 2 can sit side by side in my daily rotation.
