Okay, so I finally caved and bought this mug warmer after seeing it everywhere, and wow - it's a game changer!

The 3 temp settings are PERFECT. I start at 170°F when my coffee is fresh, then dial it down to 130°F as I sip. The color-coded lights make it super easy to see the setting at a glance.

Love that it fits all my mugs - even my giant 'World's Best Teacher' one (though it does hang over the edge a bit). The heat still transfers through the base just fine.

Pro tip: The long press to turn off the lights is clutch when I'm working late and don't want the glow distracting me.

Only wish? A slightly longer cord. But honestly, for how well this keeps my coffee at the perfect temp for hours, I can totally live with that.

10/10 would recommend to anyone who hates reheating their coffee 5 times a morning like I used to!
