Makes you wonder about work ethics over there. Why try to sell yourself as premium when you make oval holes of the wrong size. Either they do zero QC, in which case, why the premium badge, or they do QC and deliberately ship out trash hoping that the customer won't complain?
And yeah, that BB looks pretty bad, the uneven wall thickness looks pretty dramatic.
I find the whole Chinese "branded" segment that's fueled by YouTubers very confusing. On this forum, winspace, yoeleo, Seka seem to have some of the worst reputations.
