Customer Reviews
Very nice all is Ok the design and the advocat colour so beautiful i'm going to use it soon
Good! Grinds fine enough for espresso, replaced my handheld for convenience because its an electric grinder
The entire experience of ordering and it being shipped from overseas five days to the USA and the item being of sound materials was great. I really did not know this would only do a small amount of beans so that’s the only drawback for me. I should have purchased a larger capacity grinder.
Works great
Works really well. Am pleased with the purchase.
