You guys are really buying this stuff even when youtubers known for loving Chinese stuff gave it a red card?

That's assuming that Shimano and SRAM components never have issues, which is far from the case. I wasn't really paying attention when the first electronic group sets became common, but others comment that they had their issues, even on race days. I would assume they still do, to a much lesser degree, though the rare times they still have issues the problems are probably more quickly and painlessly corrected.

Also, engineering and design missteps are still non unheard of for the big boys, as stories of Shimano's delaminating cranks caused many people huge headaches and even injuries.

But I wasn't talking about the upper end of the market. I was talking about the mid and lower tiers, where electronic geoupsets can really shine on a price/performance ratio, but Shimano and SRAM keep the tech walled off to only high performance and super high price because they have no real reason not to price it as such. Now, perhaps, they'll have a reason.
