The Kalita Wave Dripper WDS-185 is a high-performance dripper that allows for even extraction when used with the dedicated Wave Filter 185. I bought this dripper in March 2024 because I liked the color. I stopped using it after switching to a 1-2 cup brewer. I hope someone else can use it. There are signs of use, which are not noticeable unless you flip it over (see image 4), so please be aware of this. - Brand: Kalita - Model Name: Wave Dripper WDS-185 - Filter Type: Wave Filter 185 exclusive If you wish, I can also include the remaining 10 opened filters (stored in a coffee shelf with the lid closed). Thank you.
