Review on Mug Warmer: Keep Your Coffee Hot for 8 Hours with Automatic Shut-Off and Adjustable Temperature Settings - Red Electric Cup Warmer for Coffee and Tea by Heather Jackson

This cup warmer works well and I mainly use it for melting butter quickly and easily. Setting 1 is the only setting I find useful as 2 and 3 don't really get hot, but I think they're great for keeping warm. The auto-off feature saves forgetful folks like me, but I figured the 'smart' feature meant I could connect to a hub for remote use so I could regulate the heat from the app . I also thought it would come with a mug but it doesn't... overall it's not that different from any other mug warmer I've used since my previous one was connected to a smart plug which allowed me to to turn it on/off remotely, but since I have to press buttons and not a power button, I can't even use my smart plug with it.
