LIGHTTELLS AW600
From the start like the LIGHTTELLS M200 is an easy and intuitive instrument to use. I compared the readings I got against several coffees from Royal Crown importers. My readings matched theirs dead on. The layout inside the carry case was almost step by step for assembly and use. I have used it to test about a dozen coffees I have on hand and everyone was easy and took about the same time. The only complaint I have is it only came with two cups for measuring with. Highly recommended for any roaster.
