The Kor One water bottle attracted a lot of buzz when it was released in 2008, and most reviewers are enamored with the trendy and sleek design. The Kor One is made from Tritan copolyester, which doesn't contain the controversial chemical bisphenol A (BPA), and has a hinged top that includes an integrated handle. The opening is threadless, which some reviewers find more comfortable, and it's wide enough for ice cubes. Numerous reviewers describe the Kor One as "sexy" or "slick," and the bottle did win the title of "best sustainable consumer product" at the 2009 International Plastics Design Competition. Still, this water bottle is expensive and heavy at 12.16 ounces. The Kor One is designated as a No. 7 plastic, so some municipal recyclers won't accept it. However, Kor will recycle any Kor One water bottle that has exceeded its useful life. If you don't care about looks or having the trendiest water bottle, the CamelBak Better Bottle (*Est. $14 for 25-oz. bottle) will save you $16. It may not be as "sexy" as the Kor One, but it's durable and BPA-free.
Numerous reviewers comment on the Kor One, but few comparative tests have been conducted so far. Most reviews are short with few details, but Amazon.com does feature a good selection of owner-written reviews. Reviews from Gizmodo.com and National Geographic Adventure magazine provide a good amount of detail.

Out of more than 130 reviews on Amazon.com, the Kor One does only moderately well. It earns just 3.5 stars, and multiple reviewers complain of various parts breaking or succumbing to wear and tear in a short period.
