Review on 🔥 Howay Pressure Activated Mug Warmer – Keep Your Coffee Hot on Your Desk for 4 Hours with Auto Shut-off and 2 Temperature Settings, 110V by Heather Hale

I'm not enthusiastic about this cup warmer because it doesn't keep the coffee warm enough - I would say around 105°. I prefer something closer to 150º. Also, the on/off button is like a hair trigger: anything touching it turns it on or off. It might be good for some users but not in my situation. However, it is better than nothing. I would recommend this to those with children who want their cocoa to be warm, or perhaps the elderly.
