Title: Do not waste your money...
Review: ...on this product. I had mine for less than a month before the Autoseal stopped working, in fact I only realized this after I found some coffee stains on my backpack. It seems like a good idea but the Autoseal with it's push-button, lever-activated seal just seems poorly executed. I'd much rather spend the money on a stainless steel vacuum cup that had a simple screw off top that you had to undo every time you wanted a sip. Is it convenient? No, but most times the simplest solutions are the best, especially in this case. I returned my cup to Amazon & will never buy another Contigo Autoseal product again.
