Good news, Walla2!
I agree with some of the other comments regarding propagation challenges for complex new technology. I'm sure Zero is exploring solutions, from call centers and subcontract tech/support centers, and will address the issues presented here much better with time. I've been in the technology start-up field for many years and understand that plateaus are often reached in technology adoption.
I'm not an apologist for Zero technical support challenges, just stating I, personally, understand and am impressed enough with the state of their product development that we just purchased another 2014 DS. My first DS had no problems beyond initial display glitch, and the second DS is being repaired at the factory, assisting the local dealer, and will be delivered to my home on Monday. Frustration, yes, and understanding it's a leading edge product with normal growth challenges that will translate to a maturing company growth stage tempers it a bit.
I, personally, feel ok with assisting and supporting a Federally supported California high-tech company start-up that is ushering more people, including me, into an alternative energies future.
