New Milton Design
The media could not be loaded. It's Milton, so quality and durability is best. No question asked. And there is space for meditation and tea bag. Love it.No water leakage and looks simple.The more design the harder to clean.There is a little smell but that just need good cleaning and keep it dry after use.

Not very effective performance
The material, designing and looks are perfect but does not keep the tea/coffee hot for more than 2 hours.
