Happy owner of Omicron Dual Kit v1.1 purchased in October 2011 from Elemental Wellness. Love this device, as well as this forum and vaporpedia. Until now, any issues/questions I've encountered have been addressed here in others' posts, and any cartridges that have not performed (except for one) have been ruined due to user error. Live and learn is indeed applicable to the Omi, while the curve is steep I have indeed learned and take it everywhere, has become my primary medication delivery system.
Last week one of the units stopped working--when plugged into the charger the blue switch light would blink twice, then three times, then twenty times, while the charger light remained green. Nothing wrong with the charger, because my other Omi charges up every time. Spoke with Julie @ D9 yesterday, initially told me to send in everything (charger, both Omis). When I explained to her that the other Omi as well as the charger functioned perfectly and that I required it for medicating, she told me to just send in the unit that wasn't working. Sent via UPS 2 Day yesterday. Have read about THC's excellent customer response, looking forward to experiencing it for myself.
