Review on ☕ WACACO Pipamoka Portable Coffee Maker 10 fl oz - Single Serve Brewer, Vacuum Pressured & Insulated Travel Mug, Hand Powered, Filter Pressure Brewer - Stainless Steel Thermo Cup by Patricia Goliday

I have tried many portable coffee makers because I travel a lot and this is by far the best if you like strong coffee. To get a strong coffee you need to let all the bubbles out and then tap the cup on something hard to release more bubbles (this takes about 2 minutes). Then, at a gentle, slow pace, rotate the container 1/4 turn (takes about 2 minutes). Pros: portability. Obvious lines showing watermarks. Easy to use Easy to clean. Cons: It takes about 5 minutes to craft. The lid has no drinking connection. You need to buy a cover separately. Doesn't come with a grinder (it would be nice to have a light grinder that could grind 2 cups).
