I bought a cup Yoyo for my father because it is very convenient mine. Same quality as I have purchased there are at least 5 years and I use almost every day. For those who never used it, it is somewhat difficult to clean the tea leaves on the filter when wet, it is best to empty by tapping the filter on your sink and let the filter dry (fully or partially, as long as it is not too wet), then you tap and all of a sudden falls, and presto! in closet!
