I still drip t home and work, but I use the tank to drive with. Started out ok, then went through some issues, read through the forums and did some minor things that have seemed to help, but I also have the first generation ones and maybe the second and so on will improve upon the wicking and such. As far as how long the atomizers last, well that remains to be seen. The convenience of them is pretty nice and yes they do seem to blow through juice......
