Customers like the appearance of the coffee mug. For example, they say it's awesome, impressive, and cool. That said, some complain about the battery life. That being said, most are happy with the durable materials and good design.

"...Impressive! Unfortunately the battery was a different story. It correctly displayed both the actual temp and the desired temp, but it would not heat...." Read more

Customers are mixed about the quality of the kitchen product. Some mention that it works well, although it can be a bit quirky with its bluetooth. A full charge lasts most of the day, keeping your coffee at your desired temperature. The heating element works great as advertised, and it works like a charm to cook soups. However, others say that they have had two bad batteries back to back, and the product has died recently.

"...I also think that while the battery is great, a way to charge it on the go should have been included as well...." Read more

"...and found that they had very little heating capability, short battery life and the cap leaked...." Read more

"...The battery lasts all day for me, and I keep the temp at 145F for coffee...." Read more

"...By 12:40 the battery was completely dead. I had only opened it twice to test the temperature with the thermometer...." Read more

86 customers mention54 positive32 negative

Customers have mixed opinions about the heating of the coffee maker. Some mention that it's solidly built and does a great job of keeping drinks hot, while others say that it only kept their tea hot for about 2.5 hours. Some customers also say that the push button controls are easy to use, while other customers say that they didn't like that the cup would heat up to the highest temperature without them knowing it.

"...Second, you can now select any temperature you'd like to maintain your drink at. This is huge!..." Read more

"...It's great at keeping things hot that were already hot, like coffee. I'll update the review on how it performs outside in freezing temps...." Read more

"...The app could use some accessibility updates. The temperature wheel does not work for those who have to use screen readers, such as voiceover, built-..." Read more

"...16 oz fluid capacity versus 12 oz for the competition- Good vacuum insulation-..." Read more

20 customers mention9 positive11 negative

Customers are mixed about the value of the kitchen product. Some mention it's worth the money, reasonable priced, and a nice product, while others say it'll leak and is not worth the full price.

"...It died recently, and it's just too expensive to die with just a year and one month of careful use...." Read more

"...while i think the price point is fine, it needs to work better for this price...." Read more

"...It's definitely not worth the full price...." Read more

"...It seemed reasonably priced, for what it does, and based on the reviews thought about giving it a try...." Read more

13 customers mention9 positive4 negative

Customers are mixed about the ease of use of the kitchen product. Some mention it's easy to use, with clear instructions and a good feel to it. However, others say that it'd be too big and cumbersome to set up. The instruction sheet is generic across all models and accessories, and the startup process is confusing.

"...Simple to use, with clear instructions.- Can separate the battery to charge separately and still use the mug.Pros-..." Read more

"Pros, works as it said it would. Keeps beverage warm. Easy and straightforward operation (not sure why anyone needs the app)...." Read more

24 customers mention0 positive24 negative

Customers are dissatisfied with the leakage of the kitchen product. They mention that the lid often leaks, the gasket was loose, and the battery leaked. The spout dribbles and spills, and it's annoying to clean. Additionally, some customers report that the product is potentially dangerous if the seal ever broke.

"...they had very little heating capability, short battery life and the cap leaked...." Read more

"...The lid is not leak proof; if you shake/drop the cup, it will leak.Out of the box, there was a paint drip (?)..." Read more

"...down to 2 due to being late to work this am because this mug leaked all over the place and continues to do so...." Read more

"...Hope was not enough! The cup slowly leaked into the element area and it failed. This is not the fault of the manufacturer. It is my fault...." Read more

24 customers mention7 positive17 negative

Customers are not satisfied with the portability of the coffee maker. They mention that it is too large for automobile cup holders, and the base does not fit in some vehicles. The unit with the charging battery is pretty big and fairly heavy. The cover is an extremely tight fit and quite frankly a bad design.

"...The cover is an extremely tight fit and quite frankly a bad design.The unit is very thick and wide and the base does not fit in some vehicles...." Read more

"...Pros- Really large and heavy (check the dimensions listed carefully and compare to other mugs that you own). This thing is huge...." Read more

"...I am an avid sailor and wanted a product that was rugged, portable and would allow me to make hot drinks, soup etc without hardwiring into boat..." Read more

"...As others have mentioned, this mug is huge! It doesn’t fit in most cup holders and with the battery pack attached, it is awkwardly tall...." Read more

18 customers mention0 positive18 negative

Customers are dissatisfied with the weight of the kitchen product. They mention that it is a little heavy, large, and bulky. Some say that the product is not worth its weight, and the unit is very thick and wide.

"...The unit is very thick and wide and the base does not fit in some vehicles. It barely fit in my f350 dash holder...." Read more

Great concept, unreliable temp sensor and battery
4 Stars
Great concept, unreliable temp sensor and battery
TL DR: great concept, some kinks to be worked out; but for someone that has been working out in the cold all day wanting a piping hot cup of coffee without running to a shop, it's worth it.Pros: As of November 2018, this really is the only one on the market that holds a charge of up to 10 hours on the go. It's Bluetooth enabled, so in theory you can set your drink up to temperature and be greeted by a piping hot cup when you get in your car. I've not tried this yet.The charger is very similar to a laptop charging cable, so if you happen to forget the charger but have a laptop on hand, you can charge it. Just make sure the specs are within 10%.Cons: the temp display is about 10 degrees off. When the cup read 130, the actual temp was closer to 120. At first I thought I received one with a bad temp sensor. But, when I went to increase the temp on the cup from 130 to 140, the cup now registered 120 then slowly started climbing to 140.For the next test, the bottle was filled with 48.9 degree water and set to a goal temp of 150. Forty minutes later with the ac adapter, the cup read 150, the thermometer read 147.7. Unreliable temp sensor?It took 40 min on ac power to get from 99 degrees to “boiling” 212. The ambient temp was 66. The actual temp registered 206.4 when the cup displayed 212. The cup will not go above 212. I highly doubt it can get to a 2 min sustained rolling boil to actually sterilize.As a vacuum sealed travel mug, it performed on par with a metal freebie giveaway mug with a clear plastic sip lid and was beaten by a $15 Contigo Snapseal Byron mug.Methodology: 3 metal travel mugs: freebie, Contigo and Cauldryn were filled with their perspective max liquid: 15, 20 and 16oz respectively. The ambient temp was 65.8 They were all filled with boiling (212 rolling boil) water from a pot. Once the boiling water was in the mugs, the temps fell to: 203.3, 205.7 and 205.7 respectively. The exterior temp of the mugs were: 69.9, 74.3 and 73.9 as measured by a Craftsman ir heat gun. The lid/ lip portion temps measured: 156, 95.7 and 77.9. once all the mugs were sealed, the Cauldryn made the most hissing sounds while the freebie was silent. The Contigo made sounds but was nowhere near as loud as the Cauldryn. After 11 hours overnight (it's a weekend, I slept in), the exterior temps all read around 68, the ambient temp was still 65.8. the lip/lid portion read: 77.9, 76.4 and 70.1. The water temps were: 89.8, 103.4 and 88.3. It was disheartening to see that a freebie mug with less liquid performed on par as the Cauldryn.The lid is not leak proof; if you shake/drop the cup, it will leak.Out of the box, there was a paint drip (?) on the inside ring on the base of the cup. This doesn't come in contact with your drink, but it makes me question the quality of manufacturing.I've already made a scald spot on the bottom of the base with my coffee with light milk and sugar after 1 use.You have to be very careful when unscrewing the base vs the battery. You don't want to unscrew the base with hot liquid inside!The rubber cover on the battery pack broke off after the 2nd full charge.The battery with 16 oz of liquid weighs 2 lbs 13 oz. In comparison, a 16.9 oz disposable water bottle weighs 1 lbs 3 oz. The bottle itself with liquid weighs 2 lbs 3oz.The battery takes 2 hours to change, but for 10 hours of run time.But one time when the cup was left in the winter car (approx temp 30-40), with full battery in the am, the battery just blinked and did not warm coffee. It seems temperamental, because the next day it warmed the coffee to lukewarm just fine in similar temps.All in all, if you want a warm drink waiting in your car after a long day of working outside, this gadget is for you. Just keep in mind the temp on the cup may or may not match the actual liquid temp.*Update 12/6/18 updated to 4 stars from 3 for their customer service.I sent them an email per the instructions in the comments to this review and they promptly sent me a new base and rubber cover!

4.0 out of 5 stars It works well and last all day for coffee. Impressed!
Reviewed in the United States on November 15, 2018
I expected it to be junk but I looked at reviews outside of Amazon (since they can be suspect) and it was generally positive. The only thing I might change if I were designing this would be that it holds about 20% more volume. Whether that mean making it taller or a little fatter, I'm not sure, but as it is it's still a great coffee mug. The battery lasts all day for me, and I keep the temp at 145F for coffee. I would't recommend trying to boil water in it from room temp, it would take some time but it will eventually get there. It's great at keeping things hot that were already hot, like coffee. I'll update the review on how it performs outside in freezing temps.

A CAUTIONARY NOTE: Don't try to remove the seal on the heating element. (see photo) It does come out, but you'll have a hell of a time getting it back in. You'll have to disassemble the component to allow heating element to come out of the housing in order to reseat the seal. It's doable with some ingenuity and resourcefulness, but I don't recommend it. (see some comments on doing that at the bottom of this review)

They get a A+ on customer service. After I unknowingly made the error of removing that seal to clean the coffee crud out, they responded the same day and sent a replacement element for the error. A generous move for what was my own error.

If you end up needing to reinstall the seal -
(The nuts holding the heating element at the appropriate height are covered in vinyl or silicone, like liquid electrical tape, you'd have to get that stuff off to loosen the nuts and free the element, but remember to recoat it so the bolts, which probably get very hot, don't melt insulation on any of the wires that might make contact inside or ruin other internal components. When reinstalling the element, make sure you took note of the approximate length the bolt protruded through the nut when you removed it. This is in order to make sure you get a good seal when reinstalling it with the seal reattached, too loose and it could leak, too tight and it could warp or damage the element and end up leaking as well. It's not something you want to tighten down firm at the nut, you're gauge that you're there is a proper seal of the silicone seal not the tightness of the nut on the bolt)
