LEXO BURNOUT Temperature-Regulating Coffee Mug with Lid, 16 oz, Drops Temp & Holds for Hours, Insulated Stainless Steel Travel Tumbler w/HeatZorb

After about 4 years of daily use, I can reiterate that the Burnout is the best coffee mug I've ever seen. I revised my review today to demonstrate that it doesn't leak (please see video). My previous comments follow: The Burnout mug is not good, it is great. The design and construction are bulletproof. I easily adapted to the design differences between this mug and the typical insulated coffee mug. After two years of daily use in harsh conditions, the mug still looks new and doesn’t leak a drop. I am now convinced that this is the best insulated mug produced. My original review follows: The Burnout travel coffee mug is quite good. It relies on the same principle that we can all observe in the evening after a sunny day: a heat sink. ( Or, more accurately, the first law of thermodynamics / the law of conservation of energy). Just as your concrete driveway, patio or a brick wall exposed to the sun all day will radiate heat for some time after sunset, this mug, through the use of materials which efficiently absorb heat, gradually releases the heat over a period of hours, thus keeping the contents of the mug warm. . In order for this mug to perform as intended, you MUST preheat the container (mug) with hot water. If you don’t do this, the mug will still efficiently absorb heat from your coffee, and gradually release it back, but this will result in lukewarm coffee for an extended period of time. As you may note from my photo, I supplement the mugs insulation with a beer cozy, as I am a very slow coffee drinker. This mug works. (obviously, as it relies on scientific principles- the system is as predictable as gravity). The great thing about the mug is that it works AND it is almost identical in size to much more common, but far less effective, travel mugs. I tried a very expensive battery powered mug which was astoundingly large and heavy, but which had a smaller capacity than the Burnout mug. The battery powered unit was not only clumsy, it failed to keep my coffee warm enough to enjoy for more than 2-3 hours. In contrast, the Burnout mug unfailingly keeps my coffee at either the “just right” temperature or very slightly lower temperature for 4+ hours -as long as I properly preheat the mug. For me, this mug has only two negatives. Over many, many years of coffee drinking, I have muscle memory which causes me to slide the closing mechanism toward from the drink side of the mug in order to close the cap. This mug closes very well, never leaked, but is closed by moving the slide away from the opening. I guess this is not a really a design issue, rather it is an issue related to a long ingrained habit I have developed. But, as a result I’ve had a few spills and the accompanying curses. The second issue is the lip of the mug. It is quite sleek. If it protruded about 1/16” of an inch further, I think it would be perfect. As it is presently designed, it is pretty easy to accidentally “lose” a drop or two with each sip if I’m not paying attention. I have not experienced this issue with other travel mugs. Summary: I love the mug, it is built like a locomotive and should last my lifetime, it can’t stop working and is good looking. A Tiny design change would make it the perfect mug, but I would absolutely purchase it again, as it is presently designed.

I originally posted a negative one star review because I found that the lid opening lever is a weakpoint. A simple thermos knock over sitting on the floor caused it to break and now the thermos was not pleasant to use. My review was poor because I sent an email to their customer service and didn’t get a reply. Apparently now two months later, I received a couple follow ups that they did indeed reach out but I never saw the replies. Why I see it now and hadn’t seen them before, I don’t know but I do get a ton of spam emails daily. So maybe it was just luck. Regardless, my wife and I still use the products daily and they work as expected. We love them. Keeps our ginger lemon tea we make daily, hot and comfortable throughout our work day. I definitely recommend them. Because of their efforts to reach out and willingness to help I have updated my review score. **** Original Review I bought two units for my wife and I and we use them daily. They work as advertised and love them despite the fact they are heavier than a similar capacity thermos. A few days ago my wife’s thermos was sitting next to the couch as pictured here and our small Yorkie knocked it over, and the red cap broke off. So now the cap won’t stay open without holding it down. I figured I’d just order a new one but on the listing it stated it qualified for a lifetime warranty. I sent an email to [email protected] on April 19 at 1:29pm PST. 3 days later and still no reply. I ordered another lid reluctantly but concerned it could break again simply by the thermos being knocked over on its side. I don’t like knocking companies for bad support because it seems the norm these days but I spent nearly $200 for these less than 2 months ago and a little piece of plastic makes using this product less desirable.

I love coffee, but I am medically limited to a few cups a day so I try to make sure that I drink what I like. I also don’t always plan ahead well. The result is that I tend to make a big cup in the morning and try to nurse it till lunch, then repeat until afternoon. The problem is temperature, how to quickly get it to my temperature and keep it there. I have several hydroflask and other brands of travel mugs, but they keep it too hot at first. This mug actually cools it down quickly, it works as advertised. The price is given on the order page, so I knew what it cost. It’s worth it to me, your results may vary. It’s a nice quality and made in the US. It’s also dishwasher safe, a rare trait in insulated mugs. My whole issue is with the lid. It sucks, rather it makes you suck the coffee out of it. There is no area for the liquid to pool up and slurp from, you drink out of a little hole on the top. It’s messy, awkward, and a crappy design. It seems like the design team started at the bottom of the mug and gave up in the top half inch. Out of 10 different travel mug designs, this has the worst lid. I can’t decide what to do with it. I would give it away, but it solves one problem for me at the expense of a different one.

Well I wanted this to be my go-to thermos main the USA well made the original lid is horrible you will have to get the optional to lids that they sell My problem is I like my coffee warmer and this cools it down right away perfect if you want to drink your coffee on the go and you're worried about it being too hot that is the purpose of this thermos so you could put coffee in at 195°, it'll drop it down two around 140 which to me is barely hot enough for me but perfect for those that are sensitive to heat heavy though for the ladies it's like a workout carrying this thing it's a beast coating on the outside is very well having any problem with it fading does fit in cup holders just note that the original lid is hard to drink from just a small opening you'll have to get the flip open lid which has a bigger drinking spout very expensive probably better options out there but this one maintains the 140 temperature for those that are sensitive so might be down your alley for that

Up front if you're wondering if the temperature thing is a gimmick: No, it actually works extremely well. I'm thrilled. The ONLY downside to this thing is the lid & open/close valve. I feel like I'm constantly trying to use a sippy cup, and the plastics feel a bit cheap when compared to the rest of the bottle. If the lid was re-worked this product would be absolutely perfect. Despite that, extremely happy with my mug and will use it until it disintegrates.

A clever idea: adding a heat sink inside the vacuum shield to reduce the temperature of too hot liquids, and allow that heat to transfer back to the liquid as its temperature falls. Unfortunately, it does not function all that well: 1. The added heat sink adds a lot of weight, and a lot of volume so that the 16 oz. capacity requires a large container. 2. The heat dissipation is very slow and even two hours after filling the travel mug, it is still too hot to drink from the mug directly, even when beginning with a cold mug. 3. Conversely, I did not have the impression that when the liquid temperature fell to tolerable levels, it stayed at those levels any longer than the Zojirushi travel mug does. The latter is much smaller and lighter for the same capacity. 4. The drinking hole ensures that you burn your lips/tongue until the temperature of the liquid drops to the comfortable level. There is no lip to allow the liquid to be sipped from a slightly more exposed area, as is true of the Yeti mug covers. 5. The drinking hole does not allow neatly pouring from the mug (as one might when filling a cup) because the liquid contents drips down the side of the mug. 6. It would be far better just to us an auxilliary cup and pour from the travel mug into cup. The only problem with this solution is that such a maneuver is difficult to conduct safely while driving. 7. So, a great idea, but it does not seem to function as advertised. It's also very expensive On the other hand, it is very nice looking, and when the liquid temperature is at a comfortable level, it is easy to drink directly from the mug.

I bought this as a birthday present for myself because I like hot coffee when I go to lunch at work. The 1st few months it did keep my coffee hot until lunch. About 5 hours later. When I noticed that after some months the coffee wasn't hot anymore I decided to put hot water in it 1st to warm up the thermos type mug. Needless to say 8 months later my coffee is almost cold when I go to drink it on my lunch break.. Thank God I also take a thermos of coffee with me since I drink a lot of coffee on my lunch break. The thermos does keep the coffee very very hot. This burnout mug was great at 1st but I have no feelings of positivity for it now. And like some of the other reviews say the design of the lid does suck. it feels like it's pushing my top lip and my teeth somewhere else. it's not a natural feel when drinking. Of course I did not like how heavy the mug is but if it's going to keep my coffee hot and at a consistent temperature so that it doesn't taste bitter when I go to drink it hours later then I don't mind. Plz fix the lid especially. I will keep using my thermos. I will keep using this cup because I don't want to spend that much money on another brand to see if it will work.

It works really well. Drops temp quickly and holds around 135F for hours. Very impressed. I usually add a little cold water if pouring in super hot coffee to get it down to temp quicker, still holds flat for a long time at 135 degrees even when doing this. I used a thermocouple data acquisition system and put plastic wrap over the top mug to create the chart of data.

I worried about buying yet ANOTHER travel mug but have had such difficulty finding one I reallt liked to use. I am a tea drinker, and the main problem I had with most travel mugs is that I would make it in the tea in the morning and it would be burning hot and undrinkable for most of the day. The travel mugs kept the tea too hot. I added ice, I removed the lid, etc but that would cool it down too much. It was a dilemma! But not now... I have owned the Burnout Travel Mug for a month and I LOVE it! Tea is still hot but has cooled quickly to the perfect temperature with their magic "rocket science" and it stays that temperature for the whole day! I find the slide mouth piece easy to drink from, though it does leak a little from that slide mechanism if it is knocked over. I would like to try the flip top that they offer on their website but they don't ship to Canada so I am waiting to see it on Amazon. The mug is well made, easy to hold and easy to clean. If I lost this travel mug tomorrow I would order myself another immediately. Worth every penny. My only wish is that they made it in white like the mugs they have on their website.

Just as the description. It drops the temperature of coffee to a point where it is easy to drink without burning your tongue or the roof of your mouth, something that constantly happens with other mugs especially when you are drinking coffee in a moving car. Simply mind blowing.

I make a hot coffee in this travel mug and it stays hot until I drink it a couple hours later - so very happy with the quality of this product. Highly recommend if require a hot or cold beverage but don't want to drink it straight away - the beverage stays the perfect temp for hours. Really happy :)

I purchased thousands of items on Amazon and this is one of the best items I’ve ever purchased It’s so useful. I use it every day and you can literally drink your cup of tea or coffee for half of the day at the Perfect temperature.
