I can attest to this. My astigmatism is pretty severe, and the lenses are useless if any measurements are even slightly incorrect.

Usually when I get new lenses I end up sending them back at least once for one defect or another. Sometimes this is the frame tech's fault, but I've also seen quality issues from the lens factory.

Anecdotal, but I have severe astigmatism and Zenni has worked well for me.
