Great product! Cute design, such a simple concept. The straw is easy to clean and can be used anywhere with anything since it has its own carry case and keyring. I do wish that the seal part was a bit firmer and a little harder to come apart, just incase. Other than that, I love it and my girlfriend loves hers.
Oh and also, the support I had before I purchased was super responsive and friendly, I would HIGHLY recommend buying this product. I can't wait to but from again, one day.
