Ninja as always been a brand I’ve trusted. I’m always on the go, so the Ninja Thirsti 24 oz is the prefect size bottle for me. I go to the gym almost every day. I mostly use it for water and it keeps it cold for a long period of time. When I do use it for soda, my soda doesn’t go flat. I’ve been using this everyday and it still looks as good as when I got it. It doesn’t leak and it fits in my cup holder in my car.
