Title: Didn't really work
Review: I purchased this for my father who about 10 times a day puts his cup of coffee in the microwave to warm it up. I figured this would save him a lot of time if it worked. However, it just didn't keep the coffee hot enough. Nice idea though.And before anyone comments saying he didnt use it correctly, he did. He poured a fresh cup of hot coffee, used this coffee warmer like a coaster. Within about 30 minutes, he had to make another trip to the microwave.
