Zojirushi SJ-JS10XA Stainless Steel Bottle Mug, Silver

Used it at Mount Everest climb and it kept my tea pretty warm even after ~16 hours out there on the summit day.I'm positively impressed.

I bought this thermos after searching for the right thermos for hot tea that I send to school with my son during the winter months.I tried Yeti’s and Stanley’s and everything in between and I am SO glad I found this thermos.It’s day one, no leaks, zero issues and my son just got home from school and the tea is STILL hot! I am wildly impressed as i definitely did not expect that after 8 hours he would still have a hot beverage.Definitely a must buy if you’re trying to get a product to keep coffee, tea, soups etc hot.I will say I preheated the thermos with boiling water as I was then making his tea and honey mix - not sure that helped or needs to be done, but can’t hurt!

Best quality thermos I own (and I own a few). I've never used it for cold drinks but it keeps boiled water hot til the next day. It never drips while pouring unless I've overfilled it. I fill the liquid level to no more than about an inch from the very top of the mouth.

Holds up heat

This is a good size thermos. It kept coffee hot for about 4 hours then warm for about 3 hours.

There is something seriously wrong with this item. When the thermos started staining I soaked it in dawn power wash for about an hour. Afterwards, when I pored out the water it was tinted brown and a lot of penny sized black flakes came out of it as well. It was disgusting looking. Under closer inspection I believe there was a lining and it had peeled off. I don’t think that’s normal. Not sure if I had received a defective product or not. I think one other person complained about that as well. I used the item for a few months before discovering the problem. I stopped using it since then, unsure if traces of particles may still be in there. I don’t know what the coating is made of and am scared it might be dangerous if too much is consumed. Would have returned it but it was too late. I tried uploading a picture but it’s tough to see the inside.I typically love Zojirushi items and this is the first time I’ve had a problem with one. In the past, I always found they produced reliable, high quality products. I don’t know what’s wrong with this one.As far as the other features:1. It did keep my drinks hot for the time period stated. 2. Didn’t leak (but you need manually push the bumped up rubber thing down a little harder to seal it well. 3. Seemed reasonably thick and sturdy.Not sure if it’s worth spending the money to see if this is going happen to you as well since it may occur after the return period.

The best thermos I've ever bought in my life.

This cup has leaked since the day i bought it. The top doesn't form a good seal. It leaks both in my backpack as well as after I pour it. The first pour is fine but the second and beyond leak everytime. Pour device and not worth the money
