Query: BonJour Smart Coffee and Tea Brewer

I was not happy with the shape of this tea brewer. The low rounded cup shape takes up more real estate on my desk than my previous mug-type brewer and gets in the way of my paperwork. The tea brewer often slid off its base that is meant to protect the surface it is resting on, resulting in wet surfaces and an unstable cup. I gave it to charity and bought another brand with the mug shape.
