Title: Interchangeable tops, and recyclable, too!!
Review: These are a great value since you can easily purchase a top separately when you need or want it (that wasn't the case with my Sigg bottle). All the tops are interchangeable on every bottle size. And, if and when the bottle has been dropped/dented/damaged one too many times it can easily be recycled at most recycling centers that take steel. Keep the caps and buy another, they'll serve you well for a long time.
