I’ve had several different coffee warmers and this one is hands down the BEST! I’m able to keep my cup of coffee nice and hot for a very long time! I put hot water in the mug to “pre heat” it for a minute then brew my cup of coffee. I can then take it upstairs and put it on the warmer base and enjoy my cup of coffee for as long as I want without it getting cold. Anyone who is tired of their coffee getting cold so fast should absolutely get this item. It’s fantastic!
