Zojirushi SM-SA36BA Stainless Steel Mug, 12-Ounce, Black

Let me start with, I am a diehard Brumate user. Due to an upcoming trip, I researched “best no spill travel mug that keeps drinks hot the longest”. A couple of tests said this ranks #1. So I bought it. I can confirm this keeps hot liquids hot for 12-14 hours! Beyond that it still kept liquids pretty warm. Was able to throw in my carry on bag and in my back pack without any leaking or spilling. This holds the same amount of liquid as my 25ounce Brumate. Travel footprint was smaller than my Brumate which was great as I traveled by train and threw it in a back pack. If you are looking to keep hot piping hot for a long period, buy it. No spill, checks this box also, slender design, perfect here too. I would absolutely buy again in another color.

Outstanding product! The gold color is beautiful. I love it so much I bought another one for my cold electrolyte water, and another to give as a gift. But what is truly impressive is that my hot tea stays the same temperature for hours, and the cup is leak proof. It is slim and lightweight so it easily fits inside a tote bag and the water bottle pocket of a crossbody bag without being bulky or heavy.

I've found my unicorn! This mug fits in my handbag, is leakproof, features a lock mechanism, and has a gorgeous aesthetic. The best part of all is that my coffee stayed HOT. I brew my coffee at 7:30 AM, commute, and then sip it casually throughout the morning. I like the button-press flip top; no need to fumble around with the lid while driving. There is also a spout, so less chance of leaks or spills. Coffee stayed piping hot long after lunch hour. Buy it!

Been using this brand tea cup for almost 10 years and it is the only cup I will ever use. i have bought it for all my family members at this point. Durable. Great gift. A little pricey but definitely worth it, because I can make my coffee the night before it it will still be hot in the morning. I couldn't ask for more. Heat retention is exceptional! lid quality is great

I was not satisfied with the performance of my travel coffee mugs, so I set out to find one that would keep my coffee hot for as long as possible. I gathered together a variety of travel hot beverage containers from my own personal collection as well as any others I could borrow. Some that I found do a remarkable job of retaining heat. Presumably, these same containers will be remarkable at keeping beverages cold as well. Don’t want to get into the thermodynamics of it, but at room temperature, the change in temperature from hot to ambient is always faster and more noticeable than the change from ice cold to ambient. OK, so I wanted to do something more than just a subjective comparison of different containers. It doesn’t do much to say my coffee is warm, hot, or scalding after 3 hours, so I decided to do a quantitative temperature comparison. First I filled them with boiled water, and then measured the temperatures over 24 hours or more. I’m uploading the results in tables and graphs. See for yourself how each one performs over several hours. The comparison includes some generic double-walled cups that might only be insulated with Styrofoam, or maybe even just air. These were grouped together as the worst performers. The best performers were the vacuum wall stainless steel cups. These were somewhat similar in performance, but there were a few that were much better than others. I recently bought a Contigo, 20 oz. vacuum wall stainless steel travel cup with a screw-on top with a pop-up opening. Nice, and much better than anything I was using at the time. Then I heard about the acclaimed performance of Zojirushi travel cups, so thought I’d try one. In short, it was amazing. If possible, it was too good, because if I filled it with hot coffee straight from the coffee pot, I ended up with coffee that was too hot to drink for at least 3 hours. Yes, I heard that complaint from other reviewers, but didn’t believe it. It’s true. Maybe not too surprisingly, one of my oldest thermos bottles was the best performer. Unfortunately, it has a vacuum glass liner and a very small opening. That makes it somewhat undesirable to use for travel or carry. Overall comments: Zojirushi containers are great at heat retention, and they are beautiful. Also, the Life Sky UQTOGB is a beautiful deep red. Life Sky says it’s red, and you better believe it’s really red, unlike the Zojirushi that claims to be red, but is really a rose or pink color. The Life Sky does not leak, even when the top is loose. The top seal is different from the similar style Zojirushi The Life Sky seal is wider that the Zoji seal, and as a result of that, the seal tightens down when the top is turned only a half-turn, and forms a leak-proof seal. If the Life Sky top is tightened too much, it gets to be very hard to loosen later. Tighten it just enough to be leak-proof, and it’s much easier to open later. Zojirushi containers do not leak, and the tops are easy to turn, but because of the thinner seal, they need to be tighter. Some reviewers say they have trouble with the Zojirushi SM-YAE48-GA, but I have had no problem at all. This one did not leak, and like the Life Sky, the seal is thicker, so the characteristics are similar. Separately, I compared a few stainless steel “sports bottles” which have screw-on tops, but do not have any pop-up covers for drinking. These are from Life Sky, Geysa, Glacier Point, and Simply Simily. Simply Simily and Glacier Point bottles were larger in size, but not so much larger in volume. They were better at heat retention, presumably because they have more space between the walls. The Life Sky and Geysa bottles were almost identical, the main difference is that the Geysa bottle has a highly polished exterior. It did not perform any better than the Like Sky bottle, which is about half the price. The screw tops were so similar that they were interchangeable between the Glacier Point, Like Sky, and Geysa bottles. One thing I noticed will all, is that at the top where there is no vacuum wall, they all get warm. These comparisons were run at 3 separate times. Once with 10 different cups of varied construction. Then 2 more times, keeping the groups among cups with similar designs. Update 3/16/16: I'm not happy with the way my graphics uploaded to this review. The original was high resolution, but Amazon reduced the size to the point that it's unreadable. So here's some raw data. These are temperatures vs elapsed time in hours & minutes. The column headings are numbered, and the number key is below the temperature data. If you look at the heat loss vs time, the best performer was an old glass-lined vacuum thermos jar with a loss of 54 deg at 19 hrs, 30 min. Second place was the Zojirushi at a loss of 61 deg at the same time. Watch for more reviews to be added to some other travel vacuum bottles.

Good

Este termo es espectacular. Ya es el sexto que compro. Toda mi familia tiene uno. El único problema es que tienes que realizar trámites y gastos de aduana. En el último pedido ascendieron a 44,40 € y el termo costaba 49,35 €. Prácticamente el doble. Por lo demás, estupendo.

Item arrived in the original package, in good order

J'ai été agréablement surprise du temps de conservation de la chaleur de cette bouteille isotherme. Je l'utilise principalement pour du thé et il reste brulant au minimum 4h. Le contenu est encore chaud 12h après. La bouteille est petite mais contient la même quantité de liquide que des tasses de transport régulière. Après un mois d'utilisation, il y a un peut de peinture qui se détache de la base, rien d'alarmant puisque je la met dans la poche latérale de mon sac à dos. Le prix est plus élevé, mais ça en vaut le prix. Petit contre, c'est que le bec verseur est un peu difficile à nettoyer.

Termos gerçekten çok hafif ve kullanışlı. 5-6 saat içerisindeki sıcak içecek ısısını hiç kaybetmiyor. Çok kullanışlı. Satıcı çok güvenilir ve zamanında ürünü gönderiyor. Eğer sizden PTT Kargo teslimatta gümrük vergisi alırsa satıcı ile iletişime geçtiğinizde bu tutarı derhal iade ediyor. Tavsiye ederim.
