I love Frost Buddy. I have replaced all of my cups with FB cups and coozies. I am a cup person-- I had over 200 cups at one point. I have replaced them with Frost Buddy and my drinks have never been colder. The To-Go Buddy is my go-to and I feel naked without it. My drinks are still fresh and ice cold after a full day of clients in my salon. I never get the 'dang, my drink is wasted' feeling, now. I also have a text going with customer service and they always take care of me and gave codes for me to use. Very prompt customer service. One of my favorite brands to use. 10/10 I recommend to everyone.
