Title: Better than nothing.
Review: This is a decent sipper. It fits nicely, sits a litter bit lower than preferred. I have two Nalgene 32 oz. Wide Mouth bottles, one with this sipper and one with the Guyot Designs SplashGuard. I have found that this Nalgene sipper tends to splash significantly more than the Guyot designs one. It works if you're driving, or if you actually stop moving and drink from it, but if you are still moving it is nearly hopeless. The Guyot designs splashguard can be sipped from even while jogging without spilling.
