      Daily Must-Have for Working at Home!
      Color: Black
      The KitchekShop Coffee Warmer is an item I use daily. I had an old warmer that had a switch on it and the light burnt out. I would always forget to turn it off and sometimes it would be on overnight while I slept or when I left my home office. Yikes! Fire hazard, right?! So I purchased this one and I love it. You can see a little review I made. This has a display to show the temperature setting on it while it's on. It has a power button, a timer button for up to 12 hours, and a temperature button. The timer is awesome because I can set it anywhere between 1-12 hours to automatically shut off and not worry about it. I usually set it for the time I KNOW I will be leaving my office so I can't forget about it. I also love the 4 temperature settings. I typically keep it at the second setting of 145 F which is the perfect temp for me. Sometimes, if I am bringing on a beverage that already started to cool a bit, I will bring the temp up to 167 F or 185 F to get it warmer faster, then set it back at 145 F. And once in awhile, if I only have a little bit of beverage left, I will be it at the lowest temp of 131 F so that it's not scalding hot when I drink it. It doesn't take up a lot of space and it's best used with mugs that have a flat bottom. If you have a concave bottom mug, the heat doesn't distribut as evenly on the mug and it won't heat as quickly and evenly. This is no fault of the product, it's science. I will say that I had an issue with the first warmer I purchased. It was not heating up as it should. Customer service was phenomenal and sent me a replacement and the replacement has been perfect. Even if this one goes out, I would continue replacing it because of the functionality, appearance, and quality.

      LOVE IT!! No more lukewarm coffee!!
      Color: Black
      I have a glass coffee mug with a slight ridge on the bottom so I wasn't sure if this would work with my mug. It did wonderfully! I found that the lower temp. is too low for how hot I like my coffee, but the next one was a bit too high, HOWEVER, it was drinkable I just have to blow on it a little. But, even if I forget, it's NOT TOO hot to where it hurts. It's VERY easy to use, and I'm old, hahaha

      Keeps my coffee to temperature
      Color: Black
      it works great at keeping your hot drinks hot, unfortunately you have to remember to turn off once you are needing to step away or leave for the day as it will not turn off on its own until about 8 hours later, drying the coffee or drink and leaving a dry paste in bottom of cup.

      it keeps my tea hot for as long as I want it
      Color: Black
      I really like the cute design of this mug warmer. I bought two so my husband and I can use them at the same time. My larger mugs fit perfectly on it. The four temperature settings, timer, and auto shut-off feature are all very useful. Now I can take my time and truly enjoy my tea.

      Love them as a cheap, effective warmer.
      Color: Lavender
      These really work well and are inexpensive ($20). I bought one for myself and my wife. Up front they tell you what kind of mugs/cups not to use, so read the information areas. We tried insulated mugs and the heat doesn't get passed the insulation barrier and the outsides get pretty hot to touch. We now use ceramic mugs and they work very well on these warmers. There are a number of temperature settings and we found the higher settings to be too hot. You will have to experiment with your own mugs to see what works. The sensor works well letting the warmer know if a mug is in place and it will shut down after 5 minutes without a mug. Unless your cat comes along early it won't get its feet scorched accidentally. The automatic timer works as advertised as well. Four stars because I found that trying to figure out how to actually turn the warmer off was a bit difficult and not so intuitive. Would definitely recommend these warmers. Hope this review helped.
