If I may add some more thoughts,
It is especially good press, as the last (Club?) Niagara had issues and forced some owners to go inside. I think it helps reassure people to see that it's not that big of a deal to go in there as long as we're careful. It's even better when guidance shows how to fix issues. Even if it just shows what a repair station had to fix.
This takes it a step further (along with other of Alex's videos) to show the engineering that went into creating the latest effects. I'd have to believe it will help sales and demand. There were initially, a lot of bad posts over the pricing. There's always sticker shock and trouble with new price increases. This video helps with the understanding behind the new designs. I believe we will see how the quality holds up. I like to see state of the art designs moving the hobby and especially O scale forward. I am again impressed with the design of this, and the Acela.
I'll have to come back and re-read this to make sure I got the point across correctly.
