Bought this to replace another similar coffee mug which broke when accidentally dropped in sink.  Had my previous mug for 5 years; although it's all glass, it's sturdy enough for daily use.  The mug's insulation keeps coffee hot while still being comfortable temp for my hands.  I brew 12 oz. coffee & add 2.5 oz of creamer which fills mug to within 1/4" from the top--which is my perfect cup of coffee in the morning.

Pros: Great value; highly recommended
