## Description

Zojirushi stainless steel vacuum insulated mug keeps beverages hot or cold for hours with an easy-to-clean nonstick coated interior, made with a special manufacturing technique to make the body ultra-lightweight and compact. The 2-step lid release process prevents excess condensation on the topper from being flung off while the lid opens and the stopper disassembles for thorough cleaning. Air vent on the mouthpiece allows beverages to flow out smoothly without gushing or overslowing. Safety Lock feature prevents the lid from opening accidentally. Bottle has a 1-5/8 inch (4cm) wide mouth opening. Made of BPA-free plastic and stainless steel.

Review: Fantastic mug (TESTED) - 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.
Review: Long lasting heat and safe materials for the health conscious. - This Zojirushi bottle is a great value for the money. I purchased the 12 ounce bottle for my tea. It's small size makes it easily fit into a backpack or bag. It's the perfect amount for tea. I brew it before I leave the house, and it's still hot hours later. For water, I would get the 16 ounce bottle, but the 12 is perfect for tea or coffee. Pros: The bottle's inside is ceramic and not plastic. Ceramic is much safer than plastic, which I try to avoid for all hot drinks. It has a strong seal. It snaps in place and does not open without being opened. The release button is convenient for your thumb, so while driving, I can click and drink. It's spring loaded, so the lid pops open. The spout has an air return, so the liquid flows freely. The lid also has a lock, also convenient to release with one hand. This prevents it from opening accidentally in a bag. It's very easy to clean. I have forgotten to empty my tea for several days. The old tea doesn't stick to the ceramic, and doesn't stain it. Hot soapy water or bleach, and a few good shakes, and the inside is cleaned up. The lid is easily disassembled for cleaning, though this doesn't need to be taken apart often. The seal and the mouth are both one-piece designs. Unlike other bottles I have used, there aren't any crevasses for residue to build up in. It's easy to wash without disassembly. Even though I misplaced this and tea sat in it for almost three weeks, after cleaning it, there was no odor or foul smells. After a wash, it was no worse for the wear. Cons: The price. I was a little reluctant at first because of the price compared to other similar items. However, the Zojirushi is so well made, you get more than what you pay for. The quality build will last for years, and the ceramic doesn't rust or break down. Even though it is priced higher, it's still a great value for the money. It has limited colors. For me, the color isn't very important, but the selection is limited. Overall: This Zojirushi is the best hot drink bottle I have purchased to date. I would gladly buy this again. I recommend this over pretty much any bottle on the market. I'd rather pay for quality than get one that doesn't hold heat or has toxic plastics leeching into the tea. It's well worth the price.

### ⭐⭐⭐⭐⭐ It's love!!
*by C***E on October 26, 2024*

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.
