I'm glad I found this forum. I only started vaping recently and thought that maybe I was doing something wrong that the smiloemizers were useless so quickly. The first one lasted about a week, second was I broke after one day trying to clean it with a paperclip (must have displaced the coil connection). I ordered two new ones and the first of those is already clogged up after one re-fill! Right now I'm on pre-filled cartomizers that I re-fill, but they get worse after each refill, so this is not a long term solution. When I have time I will go to the V4L shop in person to make sure I'm not doing anything wrong. I'm kind of annoyed with the smileomizer - if I knew they have these problems I'd just order a bunch of blank cartomizers. At least if one cloggs up it's a cost of $2 not, $8.
