Good size (for me)
Smooth button function allows fast water access
Sturdy bottle and carry loop
Hard to keep lid clean
Carry loop sticks out sideways too far
No button lock
I purchased this so I could maintain better hydration while at work/uni all day. It holds enough water to last for several hours, but is small enough to fit into my backpack's water bottle pocket. The button's action is smooth and properly weighted. The seal has functioned perfectly for me under adverse conditions, though I see potential for dirt or sand to elicit leakage. The only times I've had unintended drippage has been following a rushed filling, where some water misses the open hole and a bit pools on the level, outside surface of the bottle beneath the threads. While internal threading (like on the travel mugs) could solve this issue in future iterations, a quick flick of the bottle after a botched filling is sufficient for now. I frequently take my bottle outdoors (climbing, hiking, etc.) where it swings around, suspended by a carabiner clipped to the carry loop, and despite reasonable cosmetic damage it still functions as advertised.
I have a few complaints with the bottle design, as well as some potential solutions for future iterations:
Firstly, it is a pain to clean the lid. I use my bottle every day (it even sleeps next to me) and so it is constantly wet - perfect for bacterial growth. Access to a dishwasher might help me, but the real problem is this: while normal wide-access water bottles can be thoroughly washed and completely dried in under 5 minutes, the fancy Contigo lid can take hours to dry - much longer than I care to wait. So I often go longer than I should between washings. Solution: make the mechanism in the lid removable and easily separable.
Secondly (and less importantly), the carry loop is angled away from the bottle, causing the whole bottle to hang unevenly if suspended by its loop. The obvious function of this angle is to prevent the bottle from smacking into your nose, thereby rendering any angle change more harmful than helpful. Solution: put a much smaller loop in the center of the lid to allow for cord/cable loop carry.
Lastly, the ever-exposed button means you can't (or at lest shouldn't) put a full bottle in your car trunk, backpack etc. Solution: put a toggle-button lock on the lid.
Despite my complaints, this is a fantastic water bottle and I really appreciate the size, sturdiness, and ease of use. The complexity of the button-valve mechanism is definitely a double-edged sword, but the ability to drink from a sealed water bottle without unscrewing a cap makes it worth it to me.

I am a very picky buyer, but I happily bought this; it had all the features I wanted and looked nice to boot.
Unfortunately, I bought this thinking that it would actually live up to the claims Contigo made about it. I took it to class and next to work, but from it's first use it failed me. I opened my bag to find it had LEAKED WATER THROUGH THE AUTOSEAL BUTTON all over my papers for class. I wasn't very happy. I double and triple checked and it is indeed not leak-proof. I am very disappointed in this product.

I really, really love this bottle! Its so recommended to anyone that's looking for a new bottle. However, you must wash and dry the bottle properly to make sure it doesn't get moldy! You can't blame the company for this. I bought the two pack at BJ's and the bottle fits great in my bag!

I love these waterbottles! I love the "one-handed operation" and are totally leak-proof.
Unfortunately, because of the push button mechanism, the lid is hard to wash and dry properly, and mold starts growing inside.
