I am in LOVE!!! I have always gotten frustrated that I would have to wash out my cup after using it for coffee to use it for water and then it would still have the coffee taste. Now I can buy my Starbucks Trenta, pop in the with the adapter cap on, slide my cup in, and voila! My iced coffee has ice hours later and when it's done, the cup comes out for me to fill it with my water. I have already given the link to three friends to but it. It's also hard for me to find a color I like and the Nebula wad PERFECT. Teal and purple are my two favorite colors and the colors on my business logo. I think I may be in love!
