I’ve had that grinder for about ten years now and I bang that basket on the knockbox everyday and it’s doing okay, but I get what you mean. The hopper lid has a crack in it from falling not very hard a while ago, so I think it might just be luck of the draw as to whether one gets a fragile plastic piece.
Watch, I’m sure the basket will shatter tomorrow, now. But the good news would be that I don’t think they sell replacement parts for it anymore, so I guess I’d have to upgrade.
