The Coffee Mug Warmer has an average star-rating of 4.3 out of five on Amazon, with over 77 five-star reviews. Customers have called the gadget a ‘great little device’ that produces a lot of heat that is ‘worth the money’.

One reviewer said: “Great little device, low power, produces lots of heat and keeps a cup of tea or coffee nice and hot, great for office jobs or if your just a slow drinker, standard UK plug and moderate build quality, would buy again.”

A second wrote: “Amazing product. My dad is disabled and he falls asleep a lot due to his meds, putting this next to him he never wakes up to a cold tea or coffee, been a real life changer (literally) for him.”

A third penned: “Good value for the money, came faster then expected . Looks great will probably order another one. Easy to use and the auto shut off feature is great.”

But a fourth gave the coffee warming gadget a three-star review and said: “Looks very nice. Comes on and off automatically with pressure sensitive pad on top when you take a sip and put it back.

“It had so much potential and stops the coffee going cold so quickly but no way keeps it even close to hot. After 30mins it just maintains it at about 35 degrees Celsius. Slightly above what I would say luke warm.”

However another added: “I sit with a cat on my lap in the evening and don’t dream of moving her, so half drunk tea as I don’t drink once its luke warm. I didn’t hold out much hope for this warmer as I paid more for different models in other rooms, Like my drinks hot everywhere.

“I was wrong. It has a small footprint, no bells and whistles, it just does the job. I do use a flat bottomed glass mug and make sure the drink is piping hot when I turn on the warmer and it just keeps it hot for the couple of hours I use it, though it just keeps going if you use it longer. Only needs the first level of heating to keep the tea hot, great little item.”

Alternatively, you can pick up the USB Mug Warmer from Boots for £10. To use, just plug it into your computer or USB outlet that gives you a warm welcome to your desk every time.
