I saw FrostBuddy To Go on Facebook and thought it was too good to be true. I normally don't purchase anything from Facebook but researched online to see if the company did exist. Hundreds of positive reviews about their products. I ordered a To Go Buddy and waited. When I receive it I was impressed with the design. As I was going out for the day, I stopped for my usual large DD iced coffee at 7:30 in the morning and placed it in my new buddy. It stayed cold all day. I had ice at 4:30 on an 85-degree day. I am impressed. I ordered another for my daughter as a birthday gift.
