Don’t listen to the negative reviews
I was almost considering not buying this product based on the negative reviews I read, but I am glad I took a chance and got it anyways - because it works exactly as advertised, without any utility or design flaws. The telescopic straw does NOT collapse while using (unless you put in the intentional effort to close it), it is strong and sturdy. & the travel case does not loosen on its own, it’s as tight as it should be and will only open if you unscrew the lid. Great combo purchase for a great deal.
