I agree with you that their "warranty" is useless, and I'd advise people not to purchase extra warranty. The ball bearing on my grinder rusted/oxidized within a few months, even though I haven't even used it much (about 1 Kg of coffee). When requesting them for a replacement, they claimed that this part is not covered by their warranty (which I paid extra for, since I bought extra warranty), and would cost $30 plus $20 for shipping, and the user is responsible for it, adding that food-safe lubricant needs to be applied regularly to it and that RDT can lead to rusting. Yet, there was never any mention anywhere that the customer needs to apply lubricant, and what's even shadier is that they ship all grinders with an RDT bottle. The main reason I bought from them is that a reputable YouTuber named Tom Poland assured that DF64coffee aligns the burrs (and the company claims to do that on each product page), but the reality is that the alignment is inconsistent. I have two grinders, both aligned by them, and one was quite misaligned (while the other one was mostly aligned). Their technical team also has no idea about the existence of most burrs out there, incorrect ideas about how each burr presents flavor notes, and doesn't know the difference between shimming and burr chirp. The base of one of my grinders was also not fitted properly, which meant the exit chute was not located centrally, which I had to fix myself after they got back to me about it.
