Paid full price, not free for review or anything, and love it. Use it for coffee refills while out, don't like the waste of one-time use paper cups. Can hold upside down and not one drop spills out! Quite remarkable. Easy to collapse if you slide open the sip area (to prevent a vacuum) then just pop the bottom up. Since the bottom goes into the top, any remaining liquids will be contained inside (close sip area once collapsed). Was concerned it might not stand on its own since the bottom is the collapsible part, but the material is very thick and it stands nicely despite being full. Grip area keeps hand from burning on hot contents inside. Slide piece for sipping can be opened and closed with one hand. Very nicely designed product at a great price.
UPDATE: Nine months later and good as new. Been through the dishwasher frequently and used daily. Had a bike accident with it. Helmet and bike dinged up, but cup bounced away unscathed and didn’t spill a drop!

So I tested this product and overall is a good product, it has some down-fouls. It did get collapsible pretty smoothly and easy to get it straight and to collapse. If you don't grasp the mug by the stripe with the letters you risk, if your coffee is super hot, to get a little bit burn or feel the heat. Besides that it does lose heat pretty easily so that isn't good if you like to take your sweet time drinking the coffee. The good part is that you wouldn't spill neither a drop of coffee, this part one of my cats help when he kick the cup off the breakfast bar and you wouldn't be able to burn your mouth with the coffee because of the space where you put your mouth, is like a coffee rest-cooling space so you can drink your coffee without getting burn. The product is lightweight and is sturdy more than the collapsible water-bottles that Jerrybox sell.
