Works well.Love the size and portabilityGreat thermos easy to clean and doesn’t leakI bought one for my youngest kiddo and soon after ordered a second for my other kid! These are the perfect size for lunch time drinks. They hold the perfect amount of Powerade or choice of beverage for my kids that are 10 & 16 years old! They truly do not leak. It keeps drinks cold or hot whichever you prefer. These are easy to wash and the quality is great. The black is beautiful with a gold accent line. It does have a filter for a tea bag or in our case we use it for fruit or a slice of lemon! I highly recommend these!I previously purchase this product. Was satisfied with the size and it not leasking. I purchase it for my sister. She takes fruit juices to work daily and plastic bottles she has been using leaks.I bought several kettles, but they do not achieve the effect I want, always leak, I bought this kettle with the intention of trying, I did not expect surprisingly good, and the same as described, especially the handle on the lid, I can easily lift in the hand, and the bottle under the non-slip effect is very good, I do not have to worry about accidentally touch it will fall, is indeed a good bottle, I have bought again, to give it to my favorite peopleI like black because black is my lucky color, I looked at a lot of bottles and finally chose this one, I received the product and used it to my surprise, it was really delicate, I could easily put it in my bag and it kept the temperature for a long time, the seal was good, I didn't have to worry about my bag getting wet, I gave this product 5 stars and I will introduce it to my friends, it was a very pleasant shopping experience.
