Zojirushi (ZOJIRUSHI) Water bottle direct drinking [One-touch open] Stainless mug 600ml Navy SM-SF60-AD

This is a fantastic travel mug in pretty much every way. The bottle is shockingly lightweight, the locking lid is both leakproof and easy to clean, and the design is sleek and modern.However I was mostly interested in its ability to retain heat. People frequently rave about this mug online, and I've seen some wild claims about it working "too well". Apparently it retains heat so efficiently, that beverages are still boiling hot even after sitting around for days.That, to me, always sounded too good to be true. So I wanted to test it and see how well it works. I boiled water and filled the mug to the very top - the water was 208F right before I closed the lid. I put the lid in the locked position, and left the mug sitting on a kitchen counter. The room temp was 65F when I did this.After exactly 6 hours, the water was 173F, aka 35 degrees cooler than it was in the beginning. Still far too hot to drink, but a decent temperature reduction nonetheless. For comparison, the product details state that if a drink is 189F at 1 hour, it should be 160F at 6 hrs, aka 29 degrees cooler. So my water was 6 degrees cooler than advertised, but because my water started at a hotter temperature, that seems fair (also I realize that the product details won't be perfectly accurate every single time).I checked the water again after 12 hours (so 18 total hours since I started) - the temp was now 129F, and far easier to drink (but still hot). So after 18 hours, the water had cooled down 79 degrees in total.All of that being said, my takeaway is that this is a phenomenal mug. It kept my water hot for almost a day, and it definitely seems to work better than every other travel mug I've used (Yeti, Stanley, etc). However, the claims that the mug is able to keep drinks perfectly heated are clearly exaggerated. In fairness, I only did this one test, and it was by no means scientific or anything. But I think it's fair to say that while this is an above-average thermos, it isn't going to magically keep your beverages scalding hot for days. I still highly recommend it, as it works really well and it's just a well-made and cool-looking thermos overall.

A reliable water bottle for keeping drinks hot and cold. The spout is easy to clean. I have one that I used for 7 years. It is very well made and last much longer than my other thermos. I am getting another one for my kid. It has a lock that prevents opening the lid accidentally.

About six months ago I bought a Yeti for the first time, based on all the glowing reviews. It's okay, but doesn't retain much heat after about 5 hours, and the stainless steel is either stained or rusted (and that happened after a week). So I started looking for something better.Excellent heat & cold retention was my main criteria, but ease of cleaning and no leaking were also important. And I wanted another 20 ounce cup. I studied ALL the cups with lids and their reviews, multiple times. I was trying to pay less than the bag of gold & treasure I paid for the disappointing Yeti.One day the Zojirushi popped up. I kept passing it by because it looked like a thermos, not a cup, and the price was in the same range as the Yeti -- giving the possibility of two expensive cups that didn't work.But the reviews were stellar, some of the one star reviews were because liquids were still too hot hours later, clean up did look simple, the lock feature meant no drips, and even though it wasn't a "cup", it was possible to open & drink one handed. So I put it on my list and waited for a sale.A month and an Amazon Sale Days! later, there was no sale and I bought it anyway. I'm so glad I did. It's feather lightweight, the lock feature is secure, the design of the drinking spout is perfect, it's super simple to clean thoroughly, and the heat retention is AWESOME!!I fill the container with hot coffee before I go to bed, so that I can have coffee before getting up (I'm retired). After seven or eight hours, the coffee is only slightly less hot than it was when it was packaged. Perfect drinking temperature. I cannot believe the heat retention of this thermos. If I were going to get a drink from it after only a couple of hours, I'd probably have to pour it into a cup to cool a little. Highly recommended and well worth the price.Tip: the instruction booklet is in Japanese. If you have "Google Lens" on your phone, you can take a picture of a page, then hit "translate" to switch the page to English.

This bottle works exceptionally well at two things I really wanted: it keeps my coffee hot, and it doesn't leak.I have not used it enough to drop it, but I've read these are very durable. I hope so.One other thing: it is easy to remove and install the lid, unlike my Rtic which was really hard to twist off.

Great water bootle, one of the few that doesn’t smell after each use. Keeps water fresh and cold, and it is easy to use it. No spills. compact and slim.

Let me start by saying I'm writing this on my own I've gotten nothing to write this.So I got this as a work bottle to just keep water so I don't use cups anymore. At first I was surprised at how nice it looked and it's solid for the price I wasn't expecting that. I just wanted a cheap 2 to 4 hour cold bottle for water. Let me tell you this thing will keep cold for like 6 to 8 hours with 2 ice cubes. Shocked I tell you shocked.I've been using it daily for a week and I finally dropped it, 6ft straight onto concrete and it was full of water. A small dent a loud sound and it's perfectly fine. 10\10 would recommend. The lid is snappy and built well, easy to clean no weird small spots and the bottle itself is solid smooth metal and looks nice. I got the navy blue one.Definitely will order another in the future to have one around the house.
