I had no idea I could love a water bottle so much until now! My Lifefactory bottle was a Christmas gift to myself. It goes to middle school with me everyday. I put lemon, lime, or even both in my bottle each day. Without the straw cap, I definitely wouldn't drink as much water as I do now. I love the bottle so much that I bought one for my mom for Valentine's Day. It is a must-use for all!
