This stays in my purse everyday. I expand it while at work and collapse it when I put it in my bag. Super simple to use and very convenient. I have had no issue with leaking. Just make sure you wash it out well before first use or your water will be gross. Also, don't try to collapse it when there is water inside. It is a bad idea.
