I fell in love with coldest sometime ago. So much so I got my grandma one, my oldest daughter and her boyfriend one, my youngest daughter one, and then I had mine. Then when they came out with the limitless one, I got myself one and my grandma one. I got the interstellar because I love the colors and how they blend together is just perfect. I don’t really use the shaker top. But I love that you have the straw option. Because I have some health issues and sometimes it’s easier for me to drink out of regular straw, but I still have the option of switching to the fliptop. I look forward to growing my collection! I recommend these to anybody that comes along. My daughter went and bought a Stanley and she wishes she wouldn’t of now because it doesn’t keep her ice is cold as long and it’s really heavy! There is no way I could carry that around. I’d probably get carpal tunnel lol I hope I can gather up enough money before Christmas to get her, one of the bigger limitless ones. I highly recommend this to anyone!
