This has more than enough room for tea leaves to fully expand and holds enough water to brew an extra large cuppa (but not enough for two cups). It doesn’t seem to absorb scents/flavors of past brews hardly at all and if it does a quick rinse or light scrub will dissipate anything that lingers. (Even my Lapsangs come off easy). Mesh is fine enough for even the smallest roobios needles.
My only gripe is that cleaning it can be a pain in the butt for those of us without dishwashers. There is one small nook in particular that requires me to take a Q tip to clean out. As a result I don’t really like brewing things like David’s or Teavanna tea in it because I worry about residue getting in there and possibly molding. But if you DO have a dishwasher this shouldn’t be an issue as it is safe to pop right in there and sanitize the easy way.
