I have a fair amount of driada's products and everyone around my local area uses them, and in my experience everything seems to be well done. I have not experienced anything that was watered down or ineffective or harmful.
My only critique is that it seems that allot of their orals use the same pill press, and the only way to tell the difference between them is the blister pack before you remove it.
This could easily lead to a mistake if you don't check the writing on the blister package every time. I wish they would have a unique shape, color or marking on their different pills.
This would also help detect any manufacturing mistakes or mislabeling.
