Cute, lightweight, works as advertized!
It's petite, pink, and keeps my hot water hot for over 24hrs. This styling is very round, adding to its cuteness. Easily fits in cup holders, or a medium bag. Small, really, a tiny thing I would change, is the opening mechanism is a little higher than another version I have and slightly gets in my way when I pour water into my mouth. But, this is adorable and makes up for it. Would totally buy another one under $25 in another shade of pink, like coral. It's super light weight, which is so impressive, given its insulation abilities. I haven't tried with ice, but it's kept my cold water cold all afternoon in a hot car in 95+ degree weather.

Great Travel Stainless Steel Mug
Perfect size to carry in tote bag or purse, no spills as this has a easy locking mechanism. I have received many compliments on it. It’s compact, yet still fits a Starbucks grande size coffee and keeps it hot all day. Its a Zojirushi, excellent brand, and also make great gifts.

Best thermos money can buy
The best thermos I've ever owned. Owned it for a few months now. Seals great and easily (nothing to fidget with trying to get it "just in place"). Keeps my coffee warm not only all day, but if I forget to dump extra at the end of the day, I'll find it somehow still warm the next! (And still dumping! Haha). I love this thing and get lots of compliments on it. Can't imagine a better thermos for any amount of money.

Beautiful color & matt texture, no leak, light-weight, easy drink! But smells plastic or paint
This is absolutely beautiful and functional. I bought it to replace my old Zojirushi mug I have been using for 6+ years. The old one I'm still using, but I left it at the temple over the weekend, and I need a leak-proof mug to go on a trip. So I bought this one, out of trust for Zojirushi!

I bought it to replace my old Zojirushi mug I have been using for 6+ years. The old one I'm still using, but I left it at the temple over the weekend, and I need a leak-proof mug to go on a trip. So I bought this one, out of trust for Zojirushi! This one is a new version of my old mug. They maintained all the advantages of the old version, but made improvement on the cap. there are fewer parts on the cap, the cap doesn't fling water when i open, and the water comes out of the vent more smoothly. these are definitely improvements worth praising. However, I have only one concern about the new mug, which is the smell. I have washed the plastic parts in soap water, and washed the body of mug with boiling water for several times. however, there is always a faint smell when i drink the water from mug. i'm not sure if the smell comes from the paint inside the mug, or the plastic cap. I have been using the mug for 5 days, I hope the smell will go away eventually. otherwise I concern for my health. This Zojirushi mug is absolutely beautiful and functional. I bought it to replace my old Zojirushi mug, which I have been using for over six years. Although I'm still using the old one, I accidentally left it at the temple over the weekend and needed a leak-proof mug for an upcoming trip. Trusting in the Zojirushi brand, I purchased this new version of my older mug. The new mug retains all the advantages of its predecessor but comes with notable improvements, particularly in the cap design. The cap now has fewer parts, it doesn’t fling water when opened, and the water from the vent flows more smoothly—improvements that are definitely worth praising. However, I do have a concern about the new mug: the smell. Despite washing the plastic parts with soap water and the body with boiling water several times, there's a persistent faint smell when I drink water from it. I'm uncertain whether this odor originates from the paint inside the mug or the plastic cap. As I've been using this mug for five days, I am hoping that the smell will eventually dissipate, as it is a concern for my health.

Super Convenient and Easy to Clean
Keeps drinks hot or cold perfectly, fits easily in my bag, and is a must-have for going out. I also love that the mouthpiece can be removed and washed — a big plus!

Lightweight, leak-proof, and hot coffee all day!
Lean, mean, coffee canteen! It keeps my coffee HOT like, all day. I also really like the lid function! It pops open nicely and if you push the lid back all the way, it sorta "locks" into place so it doesn't slap your nose while you drink. I also like the lock mechanism, it's really discreet but works really well and I haven't had any issues with it breaking. It's also extremely lightweight and very easy to clean. However, it does dent super easy. It actually arrived with a small dent but at the time of ordering it, I had ordered the last lilac one so I wasn't too upset about it. I also did have to buy a water bottle brush just to clean this because the instructions say not dishwasher safe.

Light and easy to use
Super cute color and design -- fits nicely and discretely in my purse and my car's cup holder. The only weird thing is that it came with a warning saying it had a cancer causing toxic chemical? Not sure what part has this or if it's safe in certain conditions and not if it's scratched or whatever. I don't think you can put this in the dishwasher but it's easy to clean and drink out of.

使いやすい上に洗いやすいです! 娘の調乳の際にお湯を入れるマグとして使用してましたが、保温力も抜群。 お湯を入れても重くないし使い勝手がよかったです。 お色味も可愛いです!

Always been a fan of zojurushi mug. Got the 16oz ones but wanted a small one for my coffee/tea. This was the perfect size for coffee on the go and I could toss it into my work bag/purse easily without taking up too much space. Always stay hot throughout the day. Love the new design where the mouth piece is a single piece and easy to wash. I tried many coffee mugs before this one and decided to go back to the trusty zoji brand.

Excelente cantidad, funciona muy bien, mantiene bien la temperatura de mi agua fria incluso cuando lo dejo dentro del auto. Es muy compacto, entonces tambien cabe en casi todas mis bolsas.

Lo utilizo para llevar café al trabajo. Al principio aguantaba muy bien el calor durante horas, pero ahora, al haber pasado 2-3 meses ya no aguanta tanto. Las tres primeras horas las aguanta muy bien, pero despues de abrirlo una vez ya no aguanta el calor nada

Keeps liquids boiling hot for a long time. Only downside is that the drink is too hot. Mug is also very light. And the locking mechanism means one can throw it in a purse without worry. Only downside is the paint, especially around bottom edge, eventually chipped off on mine.
