when I first started seeing them in stores, I thought...WHY? Well let me tell you, I actually decided I wanted one. $5 at Wal-Mart - you wouldn 't believe how much more water I drink in a day just because of the silly straw. Plus the lid screws on, so I don't feel like I am going to spill it all over my desk.
Try it ladies - it seems to work.
