Query: I haven't had this 6 months, and it broke

I bought this less than 6 months ago, and it appears to be leaking. To be fair, I bring this everywhere, but it would be great if it was more durable. Also, this is probably the third one I have bought in my lifetime. I clearly keep forgetting, but this happened with the other ones I bought too. After a lot of use they getting little cracks and leak. Bummer. Wish I could find something this big that was more durable.
