The desing of this tea infuser is very nice, it washes well. The holes may be a bit large, so avoid the fine teas (roibos ...) or "box for" because the leaves were inevitably somewhat compressed and thus broken. (NB: The tea "Matcha" is not for the brewers, it is a powdered tea that is prepared very differently). Inevitably, if necessary there will be tea and suspended particles to the bottom of your cup if tea is not right!. But using loose tea whose leaves are "intact" and quality if possible (in my case, I drink gallons each day), so recently bought tea and securely packaged, this minute is brewing PERFECT: no silicone odd taste at all :-). I was a little scared by buying the lower part of metal coming off the top, but not this much yours when closed. I love! In addition, the cup "based brewer" is really convenient (and pretty) when you're a little pressed and do not want to make a big amount of tea I highly recommend !!! THANK YOU!
