Just started using this and I love it so far. Very simple design and super easy to use, just plug it in and it’s ready. I like that it’s not too big or chunky, it doesn’t take up much space. I love the gravity activation function, works exactly as it’s advertised. It keeps my coffee at the perfect temperature, which solves my cold coffee problem driven by adhd.
I had an old small candle hotplate-like appliance to keep my coffee warm in a ceramic mug. However, my mind is always crammed with other things and sometimes I forgot I left it on before heading to the office. Surprised I haven't burnt my home down yet.Decided I played Russian Roulette enough times and ordered this. LOVE IT! Coffee mug off: Turns off. The bottom of the warmer never gets hot enough for fire risk, and yep, my absent memory has left a mug on it for 12+ hours and I come back to a dried up glump somewhat resembling dehydrated coffee in my favorite mug, but nothing suggesting I almost got a visit from the local fire department. It keeps hot coffee warm, but not undrinkably hot like my little hotplate did. Going to order another one for the office.If there was anything to improve on, it would be to incorporate some sort of timer in it where if a cup hasn't been picked up in let's say, half an hour for a sip, the warmer should assume it was forgotten (again) and automatically turn off until the mug was lifted/placed back on it. That would be awesome!
Works as promised. Arrived on time. Product is as described. I like the neutral white color and simple design. Would recommend to others.
I've had this mug warmer for a little over a month now and love it! It looks sleek, doesn't take up too much space, and the sensor works great. I liked that this warmer was flat so it could fit any shaped mug, and it actually resists scratches unlike my previous warming tray which almost immediately started looking worn out.This tray keeps my drinks at a great temperature - plenty hot, but still drinkable. This is especially great as our coffee maker doesn't always make the drinks hot enough, but the warming tray heats it up nicely for me.Since the button sensor is so sensitive, it's definitely best to either keep this tray unplugged when not in use or put somewhere where anyone is unlikely to accidently set something on top of it that could trigger the warming tray and potentially burn the item. I haven't had any issues with this, but maybe someone with young kids or more accident prone might want to consider that carefully.It's been perfect for my needs and this mug warming tray was definitely worth the money!
I have nothing but pros on this product. The flat surface allows more flexibility on what you can use with it, along with looking slick and clean. I use my tea pot with it which is larger than a standard mug and works great. I love that it automatically shuts off when removing the tea pot. My clients often comment on it and are wanting to order one themselves.
I am a avid coffee drinker and I hate when I am working and my coffee gets cold. This is fantastic. I do not have to remember to turn it off or on. When I set my cup down it turns on and when I lift it up the warmer turns off. This was one of the selling points for me. I only wish there was a internal timer incase I forgot about the cup that it would automatically shut off after a certain amount of time. Overall this product is great.
Keeps coffee hot. I was using another warmer plate, but switched to this one since it was white and matching KY new office decor. So far I'm very happy with it keeping my coffee hot. The other one I had to put a cover over my coffee mug to retain a higher heat. Auto shut- off when mug removed. I have a good sized mug that fits perfect. Definitely worth it, in my opinion.
This is genius and great value for your money. Sometimes I get distracted and take forever to finish my cup of coffee. I can sit at my craft table for hours and my coffee is still warm. No more trips to the microwave! This gadget works by placing a certain amount of pressure on the top surface for it to begin warming (just set your mug down on it). The blue light comes on when working. It turns off when you lift the mug off the surface.
I love this thing! I’m a student with early 5hr online classes so this is very handy for someone like myself who takes their time sipping their coffee. I no longer have to get up and reheat my coffee after it’s gone cold, I just have it sit on the warmer throughout my class. I’ve had instances where I’m away from my desk and my coffee goes cold so I just put it on this warmer and it’s heats it up again. Like others have said, it’s not going to be piping hot as if it was just brewed, but it will have a good warmer temp to it. That’s not an issue for me, I like it warm. Also it’s cute, it matches my pink theme so that’s a plus.
I waited about two years before writing this review to see how it held up and it’s still working perfectly! I got this for my mom as a christmas gift and it was an absolute hit! She ended up getting my sister the same one because of how much she loves it
This thing works so well. I was looking for a mug warmer to keep my coffee and tea hot while I drink it slow and this was perfect. It’s nice because it has a smooth base and looks sleek. I got the all black. Blends right in with my desk and has 2 settings. Both work very well. Higher setting keeps hot lower setting keeps quite warm. And it’s a good size to fit all sizes of mugs and some bowls too I’m sure. Highly recommend.
Item is perfect size and nice looking. I use it every day, and am very grateful to have it!
Mug warmer is compact and easy to use. White blends in with your current decoration
First, I'll start by saying I love my warmer. It does exactly what I need it to do, keep my coffee from getting cold the moment I set the cup down on the desk. Some have commented about it not it keeping beverages hot. It will not heat up a cold beverage. Start with a hot one and you'll be fine. That said, there are a few quirks about this product. It does not work with all cups. Seems the heavier, wider cups and mugs (like stonewear) do not work as well as smaller porcelain ones. You might have to experiment to find a cup that works the best. Also, the "auto-shut off" feature is when you take the cup OFF the warmer. If you leave the cup on the warmer, it WILL STAY ON until you take it off -- and I mean on. I accidentally left mine on overnight. So always remember to take the cup off. I have my warmer sitting on a tile trivet so it's not sitting directly on any wood. Also, the plate gets hot (I mean -- it's a heating element) so if you have a cat that likes to visit your desk, please be careful.Other than that, I love it. I use it every single day.
Love this warmer. Keeps my coffee hot, and the smart shutoff is great. I particularly like the button to operate it instead of the in-line switch so many of these warmers have. Highly recommend it.
I bought this as a gift for my mom and she loves it! She always takes a long time to drink her Tea or Hot Chocolate, and it would always end up cold by the time she was halfway done. Now her drink stays warm all the way to the bottom! Absolutely would recommend if you need something to keep your drinks from getting cold!
Purchased two of these, gave one to family member and other to keep. Works just as advertised. Very pleased with this item.
Like everything about it just wish it kept my coffee a little hotter.
This mug warmer is amazing! I originally bought one for myself and then bought another one for my son's work from home office since his coffee was getting cold and he would have to warm it up in the microwave. This stays on while your mug is on it and keeps it plenty warm till it's finished!
These are our second set of the coffee warmers so we can keep some in the den and some in our offices. They keep the coffee warm, not hot, but very drinkable. Good product.
I bought this warmer twice one for both of my parents. They both work remotely and they drink coffee and tea throughout the day. They love this warmer because their drinks stay heated for hours longer than they would without the warmer. This is an great product and I close to buying one for myself.
I really do like the simplicity of this warmer. It keeps my frinks very warm, I love it. I would have given 5 stars but with no turn on/off button it comes on if you push on the one botton controlling everything. I worry cats could step on it and turn it in and get burned. So there for four stars.
We have two warmers (his and hers) and this is by far the better of the two. It's automatic, once you put your mug on it, it comes on and stays on. No switches to worry about, nothing to mess with. The temperature isn't scalding hot, but enough to keep your beverage at a good warm level. The aesthetics of the warmer work in almost any room, it's modern and sleek with the integrated glass top and thinline body. Absolutely recommend this unit!
It’s a great desk accessory. I appreciate the different heat and time options.
Turns on automatically when you place the mug on it and switches off when removed, which makes it very easy to use. The temperature stays at a comfortable level — not too hot. It’s compact enough to keep at the corner of my desk. I use it all the time while studying or reading.
