It takes almost an hour to put together after you have cleaned it and if you didn't get the straws seated completely then it leaks. My advice would be to steer clear of these.
edit, im talking abut the ones with the straws. The other without the straw work pretty well.
After seeing your post I grabbed our samples (the very bottles you see in the picture), and tested your claim in a sink with water.To take apart the flip straw cup just pop the button off the lid and slide the straw out of the bottom of the lid. The straw has a hard plastic lower portion that goes on the inside of the bottle, while the soft flexible part sticks out of the top. To put the flip straw cup back together simply slide the straw back into the bottom of the lid. Then take the button piece and fit the upper part of the straw into the notch on the button. Then pop the button back onto the lid (it should pop right on). Finally, push up from the bottom of the straw, and also pull it from the top to make sure seal on the straw is tight, but it honestly doesn't need that much force. The straw is fitted to the lid. The whole process of putting the bottle back together took under 1 minute
I'm sorry if you're having problems with your flip straw cups. If by chance you believe the units you received are defective then I would encourage you to contact our customer service department at email@example.com.
