<p class="MsoNormal">I will say that their tech support guy did at least try to be helpful, but the language barrier was really really steep and their distribution channels are less than ideal. Their response to a request for compensation was that they would
not be profitable if they had to pay for truck rolls for such a low cost item. I really dont think they GET IT. Weve been in business for over 16yrs and this one failure could easily have ended that run.<o:p></o:p></p>

<p class="MsoNormal">I cannot imagine were alone here. I was told by AP that their failure rate was 0.2%. Now, I come from a reliability engineering background in petro chemical/ big pharma where a 0.2% failure rate would be catastrophic. Can you imagine
that 2 out of every 1000 pills made could cause death? We engineered secondary systems and multiple quality checks to contain catastrophic consequences for components that had know failure rates higher than acceptable values. A simple solution to this fire
initiation issue would be a metal enclosure instead of plastic casing. That still doesnt really solve the problem of extra connections though.<o:p></o:p></p>
