14 Oz. Rechargeable Heated Smart Thermo Mug for Coffee and Tea with Temperature Control

The battery may be defective, in that it does not indicate if the liquid is above the chosen temp; It does not indicate when it reached chosen temp; it does not turn off when the mug is empty. I emailed ThermoJoe but have not yet had the opportunity to chat with someone. The temp of the liquid will range 3-4 degrees from the set temp, but once you find your range, it does work. It does a very good job if you use the silicone lid, but the hole in the lid is so small you need to slurp or suck the liquid out, and risk burning your lips. A larger hole would fix this. Someone really into gadgets may like the mug, but it would certainly be far cheaper to just use a good insulated travel mug. Further review. I kept trying to use the mug as I think the idea is great. However, the battery started turning off after about 20 seconds after I selected the temperature. I received an email from the president of the company (supposedly) saying they would replace the battery. That was 3 weeks ago and I have not heard back, even after sending another email. Don't waste your money on this product.

Lid is too flimsy, doesn't stay in place. Not sure why it isn't a hard plastic lid. Power button and temp. control buttons are cumbersome to use. Requires multiple attempts sometimes to turn the mug on and to set or change the temperature. Better than the travel mug but still needs to work better.

Love it, now that I figured the controls out! Make the instructions less complicated. Listing say this is 14 oz, probably it is, but right to the very top. Iuse my Keurig on the 10 ounce setting and makes a perfect cup! Would nut again

I love that I can carry it around and the attached battery keeps it hot, no clumsy wires.I love that I can do my thing - walk away from the cup and do other things that take time -- sometimes minutes or sometimes an hour, and return to a hot mug of liquid. Keep in mind --it doess NOT keep it as hot as "scalding" for those who prefer scalding heat. For the rest of us, the heat is great.I love that I don't need to have a hot plate to put it on - so wherever I go, it goes - no problem.I love the size. Holds just the right amount.I love the weight - super stable.I love it's shape - shape adds to it's stability -very stable, AND fits in car cup-holder and stays hot, so... quite a mobile unit.I love the rim size when I sip from it - not too thick. It's like a normal mug.I love the feel of the enamel when sipping from it.I love the soft SILICONE top vs. hard plastic. It's FLUSH to the rim - yes! It's soft. Way better than plastic. It's also very secure. Every time I rinse the cup I mildly shake it, and turn it upside down -- and the lid stays on... totally secure. KEEP THE LID ON to ensure the liquid remains hot.I invested in fast charger which is def faster than cord it came with.Now that I know I love it, I'm considering investing in a second battery, but lately am realizing I prob don't need it as it stays hot for the time I need it, PLUS sometimes I can get 2 or 3 uses under one charge. I've waited a month to review - which was hard because I was so happy I wanted to review it, immediately. I thought I'd give it a month to make sure any flaws show up. The only minor issue is that it's a little bit hard to push the buttons. But I don't mind that because - they work. And having the buttons on the battery (vs on an app) is way way way better.

ThermoJoe hit the mark. I am addicted to ThermoJoe as much I am to coffee:). I received the product in just 2 days. No more running to the microwave to reheat coffee or tea during Zoom meetings! The ceramic cup is easy super easy to clean (in less than 30 sec; I was quite amazed) and the perfect weight and size. The taste and aroma of coffee, which are so important to me, are also supported by the ceramic lining, compared to steel in other cups which alters the taste. The cup shape enhances the aroma of the coffee. The outer layers stay cool to the touch. The handle is easy to grip with the rubber slip on. The heating element is easy to charge. The blue color is cool. All in all, its a classy product, and nicely designed! It exceeded my expectations for sure.
