Caleb M.wrote a review of Sigg Lifestyle Water Bottle - Screw Top - 1.0L on August 6, 2010
The good: Water doesn't leak out, looks cool, and very light.
The bad: Dents easy, a slight metallic taste, and doesn't keep beverage very cold long.
If you just want an awesome aluminum bottle and don't care about the slight problems with it- it's a good choice. Otherwise, maybe not.
