I have a cup addiction, it seems. I have ALL of the major brands, popular brands of cups that claim to keep your drink hot or cold. Frost Buddy has basically made me pack the others (and I have a lot) into a box as they are no longer needed. I love that this is a cup holder that fits any size cup. The others I have are all cups and while most of them work and do as they say they will, you cannot use any of them for carbonated beverages. I love my Frost Buddy! I keep bragging about it, explaining to friends and family why it’s the best vessel I have purchased to date. I honestly cannot say enough good things about my beloved Frost Buddy. Do you make stickers? I need a Frost Buddy sticker now. Maybe more than one so I can advertise. FROST BUDDY IS THE BEST!
