I like the concept of frost buddy. I bought 3, one for me and two for Christmas gifts. I purchased Lagoon for myself so my review will be based on that one. The packaging kept the product safe during shipping but there was a cardboard ring around the cup with its information on it, and this ring's adhesive stuck to the cup and was incredibly stubborn to come off, with and without water. My frost buddy now has a small patch on it that is a bit annoying and I try not to touch it. The colour of Lagoon looked way cooler on BOTH of my monitors and on mobile. In person the bottom half is a sparkly deep bluish purple, but I thought it would be a bluish black. Not a huge issue but still, a second knock. The frost buddy fits in the car cupholder without issue but it only feels secure in the deepest cupholder, which is the one closest to my leg while driving. This doesn't workout too well for me personally so when I used it, I used the passagenger cupholder and just kept my right hand close by to stabilise it. I tried my frost buddy with a Starbucks large iced coffee. I found that there is too much space in the frost buddy and the coffee cup slides all the way down and the lid gets stuck on the rubber covering, risking it popping off and causing a huge mess. Very difficult to retrieve the cup and adjust it once it's inside. Might not be great for the car but maybe frost buddy is better suited for a day at the beach or camping. I haven't been able to test its capability to keep the drink colder for longer. Thank you!
