Kratom Bird - quality of new batches

I've been ordering from Kratom Bird in the past for their low prices, but there have been reports about their new (August) batches being bad - see e.g. https://old.reddit.com/r/kratomeu/comments/15xcnck/doubts_about_kratom_birds_quality_is_it_just_me/

It would be great if somebody has more info. I might do some test orders myself and report later ...
