SM-SA60BA Stainless Steel Vacuum Insulated Mug, 1 Count (Pack of 1), Black, 20 oz.

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!

Bought this as a christmas gift for someone who drives a lot. Perfect size to fit in normal car cupholders, and it does a great job of insulation... keeps the coffee hot. It was inexpensive, and looks stylish. It comes in multiple colors but I liked the black. Seems well-built.

I was searching for an alternative to the Teavana Contour Travel Tumblers I had purchased for myself and my boyfriend. We were on the "last legs" of our second tumbler each. He's a coffee drinker; for me it's tea. I knew Zojirushi was a good brand from my experiences with their various products, so I ordered two of these Zojirushi SM-SA60-BA Stainless Steel Mug, 20-Ounce, Black with very little hesitation. Obviously, as a Prime member, the shipping was great - earlier than expected, as usual for me. Firstly, cleaning. Five stars. You can disassemble the entire thing, and from inspecting it, there doesn't seem to be anywhere that the contained liquid contacts that I CAN'T clean effectively (anyone who's tried the Green Teavana Contour Tumbler knows the apparatus has one or two spots that are extremely difficult to clean well). I used Dawn Ultra Dishwashing Liquid, Original Scent, Blue, 14-Ounce , warm water, and my OXO Good Grips Bottle Brush . It was simple, easy, and I feel great about how I'm able to clean the mouthpiece/cover piece. I'll be purchasing duplicate bottle brushes specifically for his (because coffee) and mine, separate from the one I use for the "regular" dishes. Secondly, temperature. Five stars. My boyfriend came home from work the first day he used it and remarked that it "has to be made from anger and hellfire and brimstone" because after pouring his freshly brewed coffee from the carafe into the Zojirushi at 07:00/7am (approximately), it was still TOO HOT TO DRINK at lunch time - noon. He left the cover open, thinking that would help, and, after an hour, tried to drink again. Still too hot to drink (i.e., same temperature (it felt to him) as when he poured the coffee that morning). It was only around 16:00/4pm that he was able to drink it consistently without burning his lips and mouth. I, drinking oolong, experienced the same consistency of temperature - though I was able to drink mine because of the brewing temperature difference (and because, as he describes me, I "will only be satisfied if my liquids are molten or boiling." Obviously, I have no problems with high-temperature food or beverages). Lastly, appearance. Five stars. Again, my boyfriend had something to say. "It's the devil's work, and even the color drinks the light from around it!" It has a pleasant, almost matte finish, and he cannot tell if the inside nonstick surface or the outside (do I call it enamel?) are made of plastics or something else. I enjoy the logo because it's not garish, and also because that's where you line up the one-handed lock piece. I enjoy utility combined with aesthetics. Overview: Aesthetically pleasing, consistent temperature (for heat, I rarely drink truly cold beverages), and ease of cleaning. Honestly, exactly what I expected from a Zojirushi product. My boyfriend will have to find a way to deal with his temperature issues, but loves it as well. I absolutely love it, and will never look back to the Teavana tumblers. I will update this review if anything changes.

Love it. Nice size as if fits in typical car cup holders. Looks great. Hold heat long time. I tested starting with 165 deg hot chocolate (usually too hot for me to drink right away). Tested 10 hours later and had 146 degrees. Seal was tight, and I like the lock and flip that prevents accidental spills.

This all started as part of the scientist in me deciding to compare various insulated mugs etc. I'd amassed over the years. Along the way I came across lot of praise for the Zojirushi series and it's ability to keep liquids hotter than most. So I thought I'd give them a try and see how they stacked up. My testing was not lab based or anything I simply boiled water in a tea kettle, poured it in so the item was full, and measured the temperature of them after 5 hours. The gaps in temperature are large enough that I believe they separate the products based on their performance keeping beverages hot. For the test I had a Camelbak Forge 12oz, OXO stainless travel mug 13oz, Planetary design 20oz thermos, An unknown REI brand 12oz thermos, and a plastic insulated OXO travel mug. After 5 hours the results were: Plastic OXO travel mug: 80 degrees Stainless OXO travel mug: 112 degrees Camelbak Forge mug: 126 degrees REI 12oz thermos: 145 degrees Planetary Designs 20oz thermos: 163 degrees Zojirushi SM48-BA: 173 degrees Since it did so well I decided to continue the test and after 10 hours the temperature was still 151 degrees, still better than every other item I tested but one after twice as much time. It was not a big surprise to me the two thermos units did well, since they don't have easy drink tops I figured they would hold heat better. The plastic OXO mug was very disappointing just because it was one of my favorites, but I knew it didn't perform as well. So I'd have to say the clear winner in keeping something hot is the Zojirushi, I'm not 100% sure why, the unit is very light, I believe it comes down to that they've done a very good job of making sure the drinking top is well insulated. In most of these mugs you can quickly feel part of the top, or top/body interface is very hot and leaking heat. In the Zojirushi the top never got more than just slightly warm. The lock is handy for ensuring it does not come open on it's own, I've had other mugs where the opening mechanism was inadvertently activated. The only feature I wish it had is a non-slip bottom. One concern I do have is durability over time. When I picked up the Zojirushi I was amazed how light it was, however I believe if roughly handled it would dent/ding easily. The outer metal layer is thin enough that if you squeeze it you can feel it flex. In fact I believe if I pressed hard with both my thumbs in one spot I could put a large dent in it. None of the other items I tested flexed at all under any pressure I could apply with just my hands. Time will tell if it holds up, but it's certainly not going to take a beating like some of the others. So it would not be my choice for backpacking, hunting, or to toss around in the truck. However, for trips to work etc. it should hold up fine. The unit did not leak even when it was severely shaken, and left upside down for long periods of time. So I'd say if you are not going to abuse it, there's nothing I've found so far that will keep your liquids hotter longer. If they made the outer shell a little thicker/stronger I'd give it 5 stars.

Love everything about this travel canister. Hot tea in at 5pm, still warm at 6am. Sips in-between to check temperature because I needed to know. Love that fits in palms of my hand,Love the ez lock, gentle sips easily so you don't get scorched, easy clean, durable but indestructable(don't toss it off a high building). Will buy again, XOXOXO

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.
