I am happy to have bought this bottle. I was mainly important that it is tight and would not cause flooding in my book bag. And is one hundred percent that way. They also can be very clean, looks nice and has ne good amount of water. Best of all, I find the drinking spout. It can be very pleasant to drink. So thoroughly satisfied. If my sometime times should be lost, I'm going to buy exactly twice as a. My family I have already supplied with the Aladdin bottles.
