## 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: Better than Yeti ! - Bought this on the basis of reviews. Heat retention is way better than my Yeti rambler which by mid afternoon after filling up in the morning is going luke warm. This Zojirushi is about the same volume of liquid internally but has some major advantages. 1: keeps hot ALL day even after nearly half drunk 2: is slimmer/narrower body that fits into my back pocket (sticking out the top) as well as my van side door etc 3: It has a lid that flips open at the press of a button (has sliding locking switch to prevent unwanted opening) Keep dust in my workshop out of the mouth piece (unlike the Yeti which you get a mouthful of dust) (I am a Carpenter) 4: it is much lighter than the Yeti mug so would be acceptable to take walking / camping / backpacking 5: it easy to clean as the head part comes apart into pieces The only negatives is its hard to get inside to clean as its narrow but a bottle brush sorted this. Also I'm not sure how much it would take an impact if it fell while full onto concrete? Hope i don't find out because i really like this mug. Some people have said that you can't chug quickly out of it because of the drinking spout - not what you want for hot coffee anyway. But for cold it pours well like a regular flask again unlike the Yeti mug which doesn't pour as it goes down the side if you want to share your drink. Worth the money - i payed £28 for the blue one but for some reason the other colours were insanely expensive so beware.
Review: Great bottle - Was looking for a mug to take into work but that can also be used as a water bottle when taken with me on travels. Out of all reviews this brand kept coming up. You will see other brands boast 4hrs heat retention, 6hrs etc. This has surprised me. I made hot chocolate in the morning, poured some in a cup and the rest in this mug. I went out and 13hrs later, the hot chocolate was hot, not warm, not luke warm but hot. It still had that burning sensation on your lips. My room was slightly cold around 18-19 degrees. The fact it can maintain the temperature is very nice and removes the worry of if you would have a cold or hot drink after x amount of hours. The bottle being slim is a bonus. Easy to carry and easy to put into pockets. The little hatch on the lid is really good and it has a lock to prevent accidental opening of the bottle. The lid being magnetic is also a bonus, when drinking the lid stays open so it doesn't flap onto you when taking a drink. I only had it for a week so I cannot comment on the durability but so far everything is all good.

### ⭐⭐⭐⭐⭐ Stays Hot throught the day - the Zojirushi water bottle has become an essential part of my daily kit
*by P***A on 24 November 2024*

I've never been so impressed with a water bottle until I got my hands on the Zojirushi Stainless Mug 600ml. First off, the design is sleek and it fits perfectly into my bag without adding too much bulk. The stainless steel construction not only looks great but feels incredibly durable, which is exactly what you need when you're always on the move like I am. One of the standout features for me is the one-touch open mechanism. I can take a drink without having to unscrew anything, which is not only convenient but also quite hygienic when you're out and about. The insulation is top-notch. I filled it with ice water in the morning, and by the evening, there was still ice in it! On the flip side, when I use it for hot drinks like tea, it stays warm for hours. This is perfect for those chilly days or when I'm sipping my tea all day at work. The 600ml capacity is just right. It's enough to keep me hydrated throughout my day without having to refill too often, yet it's not so large that it becomes cumbersome. Overall, the Zojirushi water bottle has become an essential part of my daily kit. It's reliable, stylish, and functional - everything you could want in a hydration solution. Highly recommend for anyone in need of a dependable, high-quality water bottle
