"This is a fantastic product for the professional coffee roaster. I have used this product a few times now to verify my whole bean and ground been roast levels and it was absolutely spot on. In addition to the precision, the build quality of the device and the study travel case are phenomenal. As a coffee professional, I can say that this product is a fantastic value for the price and has exceeded my expectations. I am a happy customer."

"The DiFluid analyzer provides accurate, detailed bean color and particle size distribution results quickly. The quality of its construction and overall design is very high. It breaks down the distribution of the sample color in 7 bands and the particle size distribution into 9 ranges displayed as a percentage of the sample. You can quickly check for skewed results that may explain any issues in your roast or grinder setting.I am very excited about how this device will help me to dial in my roasts, pour overs and expresso shots!"

"Such a great scale! Works exactly as shown and detailed. This is better than my old coffee scale and looks so much sleeker I can leave it on the counter!Pros- tiny and light- very very precise (I tried with multiple other items that I know the weight of)- simple to charge, comes with a cord, and it was quick to charge- I love the flow rate for pour speed- super easy to read and use- I can see so many uses for this scale besides coffee and due to the precision it's better than any food scale I've usedCons- absolutely NONE"

"I've used other coffee scales before, but they've not been quite as precise as this one has. This scale is super sensitive so not a good one if there is a lot of vibration or movement where you place this. I really like the flow rate and automatic timer."

"This scale is very ideal for coffee enthusiasts seeking precision and consistency in every brew. This scale is compact yet highly accurate, with its flow rate tracking, auto-timing function, and precise measurement capabilities. It's perfect for improving your pour-over technique and achieving consistent results. The sleek, minimalistic design adds a modern touch to any kitchen countertop, making it both functional and visually appealing. A worthwhile investment for serious coffee aficionados to elevate their brewing experience."
