Heated Coffee Mug, All Day Battery Life, Battery Powered Travel Mug, Smart Mug, Great for Coffee and Tea, Fast Heating Technology, Portable Charger (Black 10 oz.)

Just for the record, I rarely write reviews but I thought this one was worthwhile. I like my coffee hot And I like it to STAY hot. Even using a insulated mug ,as I went about my morning, I would end up pouring some into a microwavable mug to heat up and it never tastes right after that. So as an indulgence I bought this mug to keep my coffee hot and it really does the trick; it heats up quickly and maintains it at my absolute perfect temperature and I can sip unhurriedly while I’m preparing lunches and doing other tasks in the morning. The instructions in the booklet were a little bit confusing but there is a short version right on the cup that makes it much simpler. It’s actually pretty easy. The heating element takes up some space so it doesn’t hold as much coffee as a standard insulated mug but I just pour more in after it’s empty and it heats it up so fast that I don’t find that to be a problem. I use a metal straw so I Can’t comment on how well drinking from the mouthpiece works.It certainly isn’t cheap, but it does the job and for me it was worth it to enjoy my coffee in the morning.

Bought two. Returning both. #1 Too tall for our Kuerig machine. Probably due to the battery size. #2 the cap mechanism pinches both bottom lip and nose. When trying to drink, you can't tip the mug up very high, instead you have to tilt your head back. #3 Not recommended for driving as the lid obscures line of sight. Jeez!

My husband bought this for me and I love it. I sip my coffee and usually drink 2 cups during the day. I would heat my coffee multiple time through out the morning in the microwave. This mug keeps my coffee at 137 degrees for hours.We RV travel a lot for long hours. We usually stop at McDonals in the morning for breakfast and medium coffees. Usually about a half hour down the road the coffee is no longer hot. I like my coffee hot. With this mug it keeps my coffee at 137 degrees (that is my set point, yours may be different). This mug holds 10 ounces. A McDonalds medium coffee is 16 ounces. I can fill the mug and when the mug gets low on coffee I just add the rest of the cold coffee from the McDonals paper cup and the Smarttmug almost instantly heats my coffee to 137 degrees.The flip top keeps the coffee from splashing out as we drive down the road. The mouth piece makes it easy to sip coffee and not worrying about bumps in the road. The mug will fit any drink holder in any vehicle.The battery life is great. I have never run the battery down to zero. I have used the mug for over 8 hours and still had one to two bars of battery power left.The only downside is the display is very hard to see in the sunlight and the operating instructions are not clear the first time using it.

Love the idea and design but it just doesn’t hold enough liquid. Obviously you know how much it’s going to hold when you buy it, but it just isn’t enough to warrant the purchase.

Very pleased with this purchase. The controls take a while getting used to, but once you figure out that the instructions are misleading, you'll get it. Takes a while to charge, and it doesn't heat at the same time it's charging. I use mine until the coffee is gone, then wash it and put it on the charger. Best smart mug I've found (I have some other brands that I just don't use any more). Best set-up is to have two mugs! BTW, be sure to preheat the mug, it will keep your beverage hot a lot longer that way.

This is an updated version of my happy review of the past. I got ten good months from the mug. Loved it, esp. riding all winter in the cold, it did great! Here and there it would get funky though. For instance a few times the settings got changed or power would go off by holding it to take a sip. But the end seems to have come now. It turns on but won't heat and if slow tapped to change the temp setting, it just goes to the battery icon with TEMP below it...then turns off. Their customer service has tried to help but being their suggestions haven't worked and the return period has expired, I'm afraid the bottom line is that it's way too expensive for ten months service.Update! SMRTMUGG asked me to send my mug back for either a repair or replacement and included a return address label. I'm hopeful whatever the warranty is, that it covers the cost. It may just yet be a great buy. We'll see... Thanks Chris at MSRTMUGG!Last update! SMRTMUGG sent me a new replacement for the broken mug. Perfect!!!

The battery did not recharge for me so I returned and got the ember travel mug instead (which also has battery issues but recharged well in the plate). But was able to properly boil the first time when it still had battery. Aesthetically looked very nice with nice touch control functions.
