I agree that 3-4 years ago there was not so many strains as now but the quality was at least 30-40% better. But i have tried almost all eu vendors and even now Kraatje is still better than most other vendors. Maybe i had luck to order Great White and GMD. These strains are not bad at all, especially if you mix for example Green Borneo from Kratom dudes and Great white. I can not say that all strains are good. Super Maeng Da totally sucks. I do not know about Super Green( something like that).
