Clean design, works as good as it looks!

I like the design but even with a mug intended for a device like this, it does keep my coffee hot.

It keeps my coffee or tea at a nice temperature (not too hot or cold) for as long as I have it on.

Makes an incredible gift and definitely keeps its warmth to make my coffee the perfect temperature.

This works very well, and I like the temperature it keeps my coffee.

But with this device, I’m able to enjoy the cup of tea at the right warm temperature each time & each sip

I had a business meeting with my boss where we had to leave our office for the entire day, and when I came back, my coffee was still at the perfect temperature

Designed in California and manufactured in the PRC, it's worth the price and is working just fine with a regular ceramic mug.

This warmer works well for me even with a concave bottom of the mug.

Packaging was impressive, works perfect.

Works, not to my expectations, but works.

Bought this one to replace my old mr.coffee warmer,bc it was old, but this one barely warmed up, much less warm my coffee

Perfect as a candle warmer.

It's either hot/warm or iced.

I am loving this nice warmer

The red setting keeps my coffee hot/warm at the perfect level

Sleek looking and easy to clean.

It's also very sleek-looking.

I have a ceramic warmer but wanted something more modern and sleek looking

Clean sleek look and warms up my candles without having to worry about starting a fire

I love the sleek profile of this warmer and the two temperature settings.

It keeps stuff hot very well and low profile

I like the hotter level on the device

It keeps my coffee warm at a comfortable level without overheating it like the microwave does

The red setting keeps my coffee hot/warm at the perfect level

Don't waste your time or money

I usually don’t drink my cup of tea at one go (typically takes about couple of hours to finish the cup before I refill it with hot water), and usually that means cold tea before I actually finish the cup

Thankfully, the spill was easy to clean with just paper towel & some water

I often like to drink warm-hot water and it cools down too quickly in a mug, so I typically tote around a thermos all day around the house

Have it as a gift and she loved it!

Gave my mom the mug warmer as a gift, she loves it, uses it every day

Makes an incredible gift and definitely keeps its warmth to make my coffee the perfect temperature.

The plate gets hot but my mug and coffee are cold

The blue one keeps the mug warmer at a lower temperature, but in my opinion it just keeps the coffee lukewarm

I set my mug on the device for 10 minutes and it never warmed my coffee

Gave my mom the mug warmer as a gift, she loves it, uses it every day

Started with a cold cup of coffee when I got this and tried it out on high and it actually warmed my coffee up

I love a good hot cup of coffee

Well, flat bottomed cups are not really very common

But with this device, I’m able to enjoy the cup of tea at the right warm temperature each time & each sip

The product itself is very easy to use and heats up really fast

I also love this product because it was bought from a small business

It is a horrible product.

This product is great in preparation for the cold weather

This product is weak and ineffective.
