I purchased this premium grinder in September 2024 and have ground a significant amount of flower in it since then. Overall, I’m satisfied with the product. However, the pollen screen is a major drawback. The amount of flower I’ve ground in it doesn’t correspond to the amount of kief I’ve collected, and it’s not as effective as a regular grinder for extracting kief. This is disappointing because my primary motivation for buying this premium grinder was for the milling plates and pollen collector.
