Q / p very good. The tastes of the teas are not altered, the large leaves can grow in without problem, fine teas are perfectly filtered, and it does not stick to the glass if you forget it in the glass and dry, unlike some other brands. One star less for the new opening system where he found "wise" to a kind of sticky paste called-is supposed to help (re) learn the filters. Zero points, two filters torn because of this useless gadget.
