Came here to make 100% sure the cup part is dishwasher safe, because I wanted to try it for spices. Read people having what sounds like lemon manufacturing issues. Bought Sep 9, 2019. I’ve had zero problems with the plastic lid, or anything else on the grinder. Fill, push the button and walk off to do other things. I’m terrible about cleaning it. Mostly just tapping the cup empty, and a few times wiping with a cloth because it looked crazy dirty.Used about twice a week for the last five year, to make two max capacity grinds for pouring into my long mesh filter, sitting in a 1/2 gallon jar. I’ve used all the settings a few times. (Spoiler, super fine dust gets created by all settings and I still need to strain the liquid results through a muslin.) No grind setting finer than medium seems to make a stronger batch of coffee either. Coarse grind, the recommended for that type of coffee, is a waste of beans, in my opinion. Needed way more coffee concentrate to get the same awake results vs medium grind.I have no issues with the grinder’s performance. Ordered it because of the pre-set grind settings. Perhaps in my coffee ignorance, it shouldn’t create dust, but I really wouldn’t know. Trying to find a decent tasting bag of beans on the other hand has been rough. Non-grinder related venting below-I bought this grinder because the only brand of coffee that seemed reasonable for the bean farmers kept having low stock of their pre-ground. So I ordered 20 lb bags direct.Various rancid, burnt, and wet dog flavored stuff was my frustration about every other bag. Same blend each time. Then tried small bags of their other blends. Big nope. Ordering from other companies hasn’t so far been any better.I don’t get why people even like this harsh bitter drink, when it’s normal flavored. I’m using it, after a very long personal struggle, specifically as a caffeine dosing agent. Soda, or the like are much worse, and my stomach sadly decided to reject all manner of tea about 8 years ago.
