Just to chime in here, after reading some of the recent posts (I just came back from Peru, hiked to Macchu Picchu):
The issue as I see it, and the reason for this thread, has to do with the fact that expectations are not being met. Once the feeling of missed expectations set in, every little thing becomes a frustration, and the sense of wait seems to expand due to uncertainty - with fear and anger setting in. This why we have seen, once an amp actually does make it to a customer, the anger, fear, and pain almost vanishes entirely. That's not to say the underlying problem is gone relating to SP, but it does mean that likely, a chapter is over between this particular customer and SP. At the end, we all just want our Amp.
If Mikhail would give realistic estimates, be it a year or a month, and actually delivered it, buyers would have a time frame with which to pace their expectations and subsequent choices.
Secondarily, we have the issue of his business model. This is something entirely up to Mikhail and how he wants to do business. To me, giving customers a correct or reasonable ETA isn't a business model, but part of an Ethical Business Practice. To continually default in this regard, despite ample communication or not, to me, is unacceptable. If a re-adjustment of the ETA is required, and both parties accept this additional wait - no problem.
But to be lead on like a blind mule, waiting, hoping, that this fed-ex tracking # is real, or that promised due date will be for real - _that_ is unacceptable. If Mikhail changes his business model, that is one thing, and that would likely effect a positive change. But I do not believe that has anything to do with 1) quality of amp, 2) expected reception of amp (based on given date), or 3) promises made about either of the two. A better business model should make Mikhail's business more effective. This means he should be able ideally get out more amps and sooner (one, the other, both). *** However, even with the existing model, what he says, should be taken as an expectation of what is possible under the current setup.
When one or all three of these issues does not come through - 1) amp not coming as expected (this has happened), 2) Amp not arriving when initially expected (check), and 3) revised estimates missed as well (check again) - we then have a problem. This is the nature of this thread topic - which initially came into existence due to the catalyst of not being able to find Mikail to even get an answer on items 1-3. This corresponding frustration birthed this thread. Clearly, we have seen a great deal of resonance regarding these issues here.
What this thread is NOT about is circuit design (for better or worse), serial numbers, Justin or Headamp in General. Discussing these topics can be a mere aside used to more clearly specify an on topic point, but otherwise, we just get into confusion as to what we are talking about and more importantly, what should be done.
I believe the existence of this thread, in good standing, is enough of an agent to get things moving...
