I bought the To-Go Buddy Northern Lights and I love how long it keeps drinks cold. (How long the ice lasts without melting!) Also love the color! The silicone ring is great and fits most fast food drink cups when used that way. My only issue is I'm not a fan of the flip-top lids on most travel cups like this. It's the thing that usually keeps me from making purchases from any brand that's not Contigo AutoSeal (which I think is the best type of lid and I wish more companies had similar options). Still, if you don't mind the lid or you use this cup more for your fast food cups, it's awesome. Can't complain. Would give 5 stars for the ice preservation alone. This is an excellent summer cup!
