This is my second purchase with Frost Buddy...the first one was a To Go Buddy which I love and this purchase was for 2 of the universal buddys for my husband and I. For years I have had a Thermos can koozie which it basically attached to my hand. I got a frost buddy cause I love the colors and love the ability for it to fit most drinks....I don't like it as much as my thermos can koozie, I am a can coke drinker and I just don't feel like the frost buddy keeps it as cold for one and two it seems to go flat in the frost buddy and i dont know why. I was looking into returning them but I have discarded the packaging. With that being said I love my to go buddy!!
