Large milliliter water cup fitness

Whether the material is good, whether it leaks or not, and whether it is inconvenient to drink water, I usually look at these points. For example, the American Contigo sports cup I use has no odor and contains no harmful substances, which is quite safe; Then it doesn't leak, and the cup doesn't leak, so it's safe to put it in the bag at ordinary times; Drinking water can be operated with one hand. A button can pop up the suction nozzle and you can drink water in one second. This cup suits me very well.
