Let me tell you, we had been converted Tervis people. Then, my son moved us over to the Yeti stainless cups. We have officially been converted over to the Yeti side, lol. I have tried other competitor brands, but this is my first 30oz competitor cup. I use my 30oz Yeti every day! I just love it. So, I was very, very curious and excited about testing out this competitor. I love the challenge. This mug looks just like my Yeti. It has a smaller bottom area, so it can fit in my car cup holder. I will not use a cup, if it doesn’t fit in my car. My throat swells shut all of the time due to numerous life threatening allergies. My throat is always swollen and sore. I always have a cup fully of an icy drink to sip on, 24/7. My throat wakes me up during the night, and I sip on the icy drink. It really helps. So, it is very important to me that my cup can keep my drink cold for an extended period of time. I did an ice test on this cup first thing. I filled it to the top with ice, and then placed the top on. The top has silicone rings around it, and it creates a great seal. Mind you, there is a drinking hole in the lid. You can fit a narrow straw through this. I have thin stainless steel straws that we use with these cups. After 25 hours, there was actually still some ice left in the cup. It performs as well as my Yeti, which makes me very happy!!!! It even comes in 8 different color choices, for no additional cost. It is made out of 18/8 stainless steel, and has the double wall construction. It is toxin free, chemical free, and safe to drink both hot and cold liquids out of it. My husband took his coffee to work with him. He had a 3 hour drive to the office, too. He is very happy with how this cup is performing with hot liquids. The double wall construction is great. I wouldn’t have it any other way. The cup never sweats. It is comfortable to both hold and drink out of this cup. You can put steamy hot coffee right from the Kuerig in here, and not feel the heat through the cup. We haven’t been able to find any negatives with this cup. It has held its own against our Yeti. Enjoy.
