## Questions & Answers

**Q: Hi, is the inside of the thermos will be stainless steel or plastic.**
A: Not sure of your meaning. The beverage chamber is completely steel. However the thermos cap and the inside of the cup are plastic.

**Q: I'm looking to replace the cap for this type of thermos. My old cap looks just like the one for this thermos but my thermos is 750ml. Is there any chance that the caps are compatible with different size containers?**
A: Hello, I saw this question and I have the same problem. I was wondering if using this cap as a replacement worked or if you end up finding a different solution. Thanks!

**Q: Is stainless steel supposed to rust? Had it less than a 2 months and is begging to do so. Also its leaking if its tilted a certain way. Is this normal**
A: If it is begging to do so, let it.  But if it is beginning to do so, don't.  That is the whole idea behind stainless steel:no rust.  If it rusts, it isn't stainless steel.  I have never heard of a leaking thermos bottle but if it does, it can cause a huge amount of damage, particularly if it is in the same briefcase as your computer or important documents.  I haven't got the slightest idea what you bought or got, but for God's sake:get rid of it.

**Q: Do these new push buttons caps glog up like the old ones do?**
A: Not sure, I used the button once and had a hard time getting the last few dribbles of liquid out of the cap. It caused a bit of my beverage to,leak out of the outer lid. Now I only unscrew the cap to get my coffe out

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent!
  

*by S***G on Reviewed in the United States on September 29, 2018*

This is a smaller version of a flask I already had and this size is perfect for me.  It is very handy to carry and it contains just the amount of coffee I want to have with me when I leave home. Also, the small diameter fits the small size of the cupholder in my 2000 Subaru.It keeps my coffee hot for many hours --- as hot as I choose. It does not leak at all.  The way I use this is to drink straight out of the flask. I can keep the liquid hot by just placing the lid over the top without screwing it in. The 2 inches of plastic of the lid insulates very well.I do not use the cup and I do not use the mechanism of the lid. I found that trying to drink with the lid on and the mechanism open causes the liquid to spill all over my face. This is DANGEROUS if the liquid is hot.The lid and cup should be rethought and redesigned in my opinion, but in spite of this, I give the item 5 stars and rate it excellent. It is the by far the best small travel coffee mug I have been able to find, after many years of trying just about everything.

    Good combination of cost/size/thermal efficiency
  

*by B***T on Reviewed in the United States on November 4, 2015*

This small (1.4 cup) thermos is just the thing for packing light.  After a few weeks use I've found no leaks, and no failures of the pop-up lid (which allows pouring the contents w/o removing the entire lid/seal.To be fair it does not keep the liquid as hot as my large (1 qt) "Thermos" brand stainless steel thermos; however the Uniware thermos doesn't hold as much liquid so it starts off having less heat internally than the 1 qt model.I've found that the liquid, after 7 hours, remains warm - not too hot to drink but not so cold as to rendering the liquid unpalatable.I'm rating it at 5 stars (even though larger thermos bottles may be more efficient in retaining heat longer) because of the cost/size/efficiency combination.  I'm quite pleased that I do not have to carry a bulky thermos; this one fits into my laptop messenger bag or my lunch bag easily and gives me the lunchtime 'boost' of coffee that I want.HTH

    Perfect! Exactly What I Expected

READ EVERYTHINGI enjoy writing reviews for Amazon. I am a student and it sharpens my creative writing skills. I also love critiquing reviews written by others because it aids in determining if a product is a good value. This can be difficult at times because the bad reviews send mixed messages. After reading the product description "thoroughly" and converting 350 ml to ounces, I decide to purchase the bottle to transport my diluted espresso to lecture.VALUATIONYou have to know a little about the type of product you are purchasing and its usage. The conversion was under 12 oz, which was perfect for my book bag. It is stainless steel construction inside and out making it durable and easy to clean with a bottle brush. When I received the product I inspected and leak tested it and found no flaws, then proceeded to sanitize it. I like to lightly coat all seals of this type with coconut oil using a cotton swab (chap stick works good too). It will extend the life and insure a proper seal.REVIEWWith thermal bottles, you have to help them keep your beverage at the desired temperature. If you put a hot beverage in a cool container the heat will immediately transfer from your beverage to the container and stabilize.....a simple law of thermodynamics. Start by adding simmering hot water to the container first. This will insure sterilization and warm the inside of the container. When your beverage is ready, i.e. coffee, pour out the hot water and immediately fill the container with the coffee. I assure you that your beverage will stay hot all day. Mine did! For cold beverages, start with iced water. Again, pour out the water and replace it with the beverage of your liking. Regarding the comment on aftertaste bleeding into your beverage, there are process oils used in the manufacturing of metal products. This is manufactured in China and I am sure they did not sanitized this for your protection like they would have in the States. Wash the bottle thoroughly with a bottle brush or shove a soapy rag into it. If you change beverage types frequently you will have to do this frequently to prevent bleed over. If not, a thorough rinsing will suffice. I like coffee, and the bottle "seasons" to the taste of coffee with just a rinse. Their was a comment about the bottle being hard to clean after leaving a beverage in it for several days. Neglect is a poor excuse for a bad review.CONCLUSIONI can find nothing wrong with this product. The type-size-build all adds up to an exceptional value if cared for properly. This size may be to small for some, but not for espresso with a little water. It's Perfect!
