I have bought several of these bottles over the years and will continue to buy them (as long as I lose my Nalgene bottle every 2-3 years) buy this item. Before I get on the subject, here's some background on me: - I've been drinking liquids for over 27 years - I drink 3-4 servings of Nalgene water daily Okay, now that you have my references, here's my take on the Easy- sippers Before the Easy Sipper, I would often spill 10-15% of the water from each Nalgene sip right down my cheeks and down my shirt and sometimes down my crotch. This personal defect would be more pronounced, like a passenger in a car. Depending on unpredictable starts or periods of delay, spills can deplete about 25% of my water supply. Enter Easy Sipper. In a simple statistic, I've gone over 5 days (at the time of this review) without spilling a single drop of water on myself. I can share my water bottle with my 2 year old nephew and even HE can drink freely without spilling anything. Yes, a person with 2/27th of my experience can drink from Nalgene without losing an ounce of confidence. Guess what he's getting for his 3rd birthday.
