Best praise vs top criticism for Kingrinder K6
Best Praise
+103 pts“Plastic V60, Kingrinder K6, Cosori Gooseneck Kettle w/ Preset Temperature Control, cheap food scale. Should put you around $250 max with at least $50 to spend on beans.”

+49 pts“Yup that's what they do sometimes. Spike the price up so that they can put it on "sale" and you end up only saving a buck or 2. I've been watching the K6 grinders and they went up 30 bucks day before they went on sale. And with 20% off new price you only save $5. Total scam, but I guess something is better than nothing.”

Best Praise
+149 pts“This sub has its head up its ass. Yes it’s more than enough grinder for almost anyone. Ignore the fools pretending you can’t enjoy anything below French roast without 10000 mm flat burrs. That is a headass take Realistically it was hard to beat the work flow, form factor, and design of the Niche for single dose grinding. But it really hasn’t been a leading $ value grinder since it completed its indiegogo campaign IMO”
