i am talking dead, or so unsatisfactory there is no point using it anymore.
My first atomizer died on it's 16th night as it became victim to a cleaning cycle. The next morning it breathed it's last breath. I now have a new one that is just 1 day old. I'm still working on breaking it in and it seems every new drip brings a bit more vapor. I'm also no longer using cartridges as I believe they played a part in the first one's death. So far the results have been quite nice.
I wouldn't know how to tell how long mine last. I have 5 with another on order. I switch them out constantly and don't keep track. Are most people using the same atomizer until it dies and then moving on? I think I got my first shipment about a month ago, but all the equiptment seems to be working fine. Maybe it's because I switch them out so much???
