Query: A must for tea lovers

Tea lovers know that loose tea is much better than teabags (which usually contain chopped up twigs and don't brew correctly). This little device allows you to add your tea and hot water, steep, and then easily strain into your cup just by placing the teapot on top of it. It's especially good for teas that re-brew well, such as oolong.
