Your upgrade program check box doesn’t update the price to pay!
Will you have wind sensor for rotating mast plus a sync between two Vakaros? This was promised a long time ago…
And I find that you could have given a much better upgrade deal for v1 (200 is Peanuts)
Typical for upgrade programs, you get the upgrade discount applied (to your payment type) after you send in the old device. Logicialy, commercially and practically its the only way to do these things, and thats spelled out in the upgrade FAQ.
As for the amount, yes clearly it possible to get more for the device on the 2nd hand markets, and we expect many new owners will do that. We're offering the program as a way to get the end-of-the-day cost down, a convenience, and a little bit of marketing. If you look at the numbers commercially, it not hard to see that with the original discount plus fair market value for a used Atlas 1, there not much money left.
