USB Smart Coffee Mug Warmer -
This Coffee Mug Warmer was a gift for Christmas and was well received. Nice to enjoy her tea while keeping perfectly warm. The product is as described. Thank you.

daughter loves it
my daughter uses hers every day. She uses it for everything from keeping her coffee & tea warm, to making ramen noodles. It has excellent temperature retention, & control. One warning, though. She actually put a big stack of mail on it, & after a week of vacation, she found the mail was singed. This is pressure sensitive. It turns off automatically, & comes on when weight is applied.

Why did I wait so long?
Most mornings, I drink two large cups of coffee (16 oz) while catching up on news from YouTube and/or social media. I make instant coffee with boiling water from an electric kettle, so it’s crazy-hot when I first sit down with it. But I’m not a fast drinker, so I would typically end up drinking the last 1/3 at room temp. Finally broke down and bought a warmer. I like the fact that this one only turns on when the weight of a cup pushes the device down and presses the switch button on the bottom. This prevents fires from carelessness, as it sits on the table next to my recliner where I eat, watch TV, use the laptop, etc. The table is always cluttered, but I don’t worry about napkins or paper getting hot because they don’t weigh enough to activate the switch. Device keeps the mug and contents warm. It makes the bottom of the mug hot to the touch, but not so hot that it’s dangerous to set the empty hot cup on a paper towel or coaster when the coffee or tea is gone. My only wish is that the footprint were a wee bit smaller. It takes up quite a bit of room on my side table. Heating surface could be a full inch smaller in diameter and still easily accommodate my oversized mug. Still love it, though!

So far so good
Better than other one I bought as it is still working. Not five star because pressure switch is a little sticky and sometimes I have to hit the table a bit to turn it off.

Delighted with this!
This little gadget makes me so happy! At last-my coffee and tea stay hot! Not just warm, but hot! I was worried that mugs with a foot wouldn’t stay as warm as those with a totally flat bottom, but so far every mug I’ve used has worked great. I like that it is weight-sensitive and turns off automatically if nothing is on it. No buttons to mess with, just an indicator light to show that it’s on.

Product has no auto shutoff or temperature control
I had bought two for my wife.. one for the office and one for the family room... the office one quit after the first couple of days. The family room one was doing it's job at keeping coffee warm, however today it almost caused a fire. When it heats up, (by the way it does have a microswitch to turn it on and off when the weight of a cup is pushes down on its surface), its keeps on going and as you are not able to control the temp of the surface, there is no way to turn it off if the microswitch fails. It gets so hot that it will melt objects, burn paper and fuse plastic to it's surface. Fortunately the smell of burning gave it away and I was able to unplug it. I can't imagine what might have happened if we had gone out for the day. This also can seriously burn you. I would not recommend this product to anyone. I have attached photos of a book that was burned and plastic that melted onto the surface.Paper burns at around 451f. Amazon should not be selling this product. It's a safety and fire hazard.

Great
Set the mug on it and it automatically turns on the heat and stays on as long as mug is on it. Blue light will glow too. Usb port in front does work to charge iphone. Power cord is right length.

Product works well and is non-atrusive, plus the USB connection comes in very handy
Great product!! Delivery in my area- not so much. I only have mine because of honest neighbors. After using it a few times the smell of burnt plastic and electronics became to unsettling, no longer safe for use.- Not recommended
