Query: How Do I Use It?

Should A Water Bottle Come With Instructions? The Answer Is Yes When Refering To The Camelbak 32Oz. Better Bottle. The Bite Valve Is And Still Remains A Mystery To Me. I Bite And Have Flashbacks Of A Baby Bottle Nipple. Not Enough Liquid Entering The Mouth. I Took The Valve Off And It Works Better For Me. Although Without The Bite Valve The Bottle Loses Its Spillproof Lable. Inovative Handle Molded Onto The Bottle Cap. Plus Bottle Appears To Be Very Durable.
