The Douup Manual Grinder is a slightly better-quality version of the JavaPresse, which is among the most popular manual coffee grinders on Amazon.
Performance-wise, the two are pretty similar. Adjust the grind size with a knob at the base of the grinder, and the tough plastic exterior makes it great for travel.
A big difference I do like: This Doupp grinder has a transparent collecting container, which makes it easy to see how much coffee you've ground.
The most notable new feature is the folding handle, which helps it back away discretely.
My biggest complaint is how difficult it is to get beans into the grinder.
The Douup Manual Grinder isn’t dishwasher safe, so you have to clean it by hand. This includes disassembling the grinder, though that’s easy enough.
The Douup Manual Grinder’s durability is on par with the others on this list. The plastic is more shatter-proof than the glass jars of the Khaw-Fee and KONA grinders but lags behind that of the top-ranked Culinary Prestige.
