I recently recieved the Ninja US-Ninja Thirst 24oz Travel Bottle and it's pretty nice to use for keeping your drink cold. I love to drink water all day long while I'm working. I have been taking the ninja travel bottle to work and the results of using it have been amazing. Not only does it keep my drink cold all day but also holds ice all day long. The cup is made very well, love the twist top, makes it look very innovative and easy to use. The color is even amazing. I have recieved alot of comments about my travel cup that my coworkers like it and now they want one. I want a bigger ninja bottle now to hold more water and last me all day.
