Review on ☕ Misby Coffee Cup Warmer with Auto Shut Off for Desk, Office, and Home Use - Black by Michael Hudson

I got the heater as a gift. I love coffee and would rather drink it from a regular mug than a travel mug. For this reason, I constantly reheat in the microwave. That warm UI is nice from the start, has a sleek design, etc. I love that it only appears when you press your mug. I tried it first with slightly warm coffee. I left it on the heat for about 20 minutes. It didn't get warm, but I thought it was because the coffee wasn't very warm to begin with. So I poured a new cup and put it on warmer and then called. I was excited to take a sip after about 15 minutes. Unfortunately, my coffee had already cooled down to room temperature, although it was warmer. The heated platen is definitely hot, my mug touched, etc. so I'm not sure what the problem is. I had high expectations for this product and will try again. But I have a feeling it will be a failure for me.
