[Expired]Owala Water Bottles

: What age group of kids is this cup suitable for? I want to buy a water bottle for my kid to take to school. 这杯子适合多大的小朋友用啊，想给娃买个水壶带去学校用

回复 @匿名用户 : [laugh/cry] Exactly, it has to fit in the side pocket of the backpack. Otherwise, just imagine carrying a 32oz or 40oz water bottle filled with water—it's quite heavy. I have two 40oz ones myself, and I only use them for the gym. I only let my daughter use such a large one when she's training continuously for 2 hours and even then, I have to help her carry it . A 24oz is definitely enough for an elementary school student; it’s sufficient for use at school. 对，得能放进书包侧兜才行，要不你想想一个装满水的32oz或者40oz的水壶挺重的，我自己有两个40oz的，只有健身才用，我女儿连续训练2小时的情况我才会给她用这么大的，还得我帮她拿24oz给小学生我觉得足够了，在学校是够用的

: Indeed, and the spring/latch on the lid breaks 得确，还有盖子那个弹弓会坏

回复 @JM22 : The lid on my 40oz is really hard to close now, and I have to manually open it. I feel like the spring mechanism might be about to break . But I bought a 32oz yesterday, and the lid works fine. I think I got a bad batch—when I bought the 40oz, I tried several and they were all like that. 我买的40oz盖子现在很难盖上，而且打开要自己开一下。我感觉我那个弹弓可能也快坏了。但是我昨天买了32oz的，盖子没什么问题。我感觉我那批不好，我买40oz的时候挨个开了开都那样
