This pot works best for unrolled oolong and black tea. It is able to fit about 8 grams of ball rolled oolong but has trouble closing with 10+grams of oolong after they unfurl. Unheated, the pour time of a full pot is around 11 seconds. Heated, the pour time is lower at 7 to 8 seconds, likely due to expansion. Pour time is also generally below 10 seconds when brewing non-ball rolled oolongs, but can be up to 20 seconds with ball rolled oolong. This makes precision pouring with ball rolled difficult. The lid sits somewhat loosely on the body. When cold, the seal is good: when a finger is pressed on the hole on the lid, the flow stops. However, when heated, the seal is not as good, and tea can easily drip out from between the lid and the rim. The poor sealing can be mitigated by making sure the lid is also hot so that it has also expanded like the body. Also pushing the lid forward towards the spout helps. Overall, this isn't too bad of an issue, but the seal is definit...
