Last Christmas my wife got me two different sized Mizu water bottles, I've used one of the two everyday. I noticed a month or two ago that one of the screw on caps was retaining water inside of it and I couldn't get it out. This drove me crazy so I sent an email to the people at Mizu, time passed and I forgot that I even sent the email. Flash forward a month or so, and I receive an email from them apologizing for the delayed response (my email was stored in their junk folder, spam) and notifying me that some new caps were on their way to me. They showed up a few days later along with some stickers and a note from Jussi (Oksanen, pro rider and owner of Mizu). I was extremely impressed with the service and response that I got from Mizu and thought it merited some recognition. If you haven't yet switched over from buying countless plastic bottles and just tossing them in the trash afterwards, please check out Mizu ( http://www.mizulife.com ) and support a company that's run by snowboarders/skaters and out to help make the world a better place.
