Hello and good day I have the basic question, what to hold of the different suppliers/manufacturers of discs and coverings. So far I have always bought ATE. Is this exaggerated and what do you buy ? Surely there are parts that come with different stickers from the same production. That is in other areas – e.g. refrigerators – also so. There have already been messages about wavy – warped discs. I have never had that before. R
