Review on ☕ Gynnx Coffee Cup Warmer: Efficient Desk Companion with 3 Temperature Control Modes by Amy Cummings

I love the blue water drop icon that lights up on the black heating surface when the warmer feels the weight of the mug. It's nice to come back to a warm cup of coffee after being busy with other things. It slowly heats the coffee mug from room temperature to pleasantly hot. I've used it successfully with a mug that has a notch on the bottom. My new best friend on the desktop! :)
