I have absolutely no complaints about this kettle. The mesh on the infuser is incredibly fine and will only let the finest of powder through - unlike other diffusers I've used which let even medium sized leaves right through the mesh and into my tea. The size is perfect for 2 decently large size cups of tea. I bought this for my girlfriend but honestly ive probably been using it more. She loved the rose blossoms though (as did many of her friends). Highly recommend! You will not be disappointed with your tea brewing experience.
