Klean Kanteen  TKWide Insulated Water Bottle with Twist Cap - 20 fl. oz.

I had my doubts when I was buying this bottle, but gave it the benefit of doubt. Decided to test it and filled it with water and left it overnight upside down on a plate. Sure enough there was an ounces of water on it in the morning. Thought that maybe that water was trapped in the lid, but the more I shook the bottle, the more water would drip out. The bottle can't be trusted to be in the backpack or any other bag where it may get inverted and/or shaken. I think that lid has a fundamental design flaw where the liquid that enters the internal metal straw would eventually leak out. Needless to say, it's going back.

I bought one for myself and just by looking at it I thought it was great quality so I purchased three more for gifts. When I used mine it whistled and screeched when drinking. I looked up reviews online and a majority of them had the same problem. One helpful comment said the cap is too tight if that happens so I tried again and the whistle stopped. Retained ice for the five hours I was on 85 degree beach. Adjust the cap if yours squeals when you sip. I also had fluid in the sliding part every time I opened it so be careful opening. Poor cap design. Others replaced with chug cap but I'm not putting more money into it.

Cute bottle . However, the squeaks and whistle while I’m trying to drink is annoying for such an expensive cup! 

Great to tote around. I use it daily for work for mywater or protein shakes.

Love the color and size convenient to travel! ♥️ Must have ♥️♥️♥️

Bought this Klean Kanteen for my son. It is a great size for him and keeps his water cold as expected. The thing I like the most is that it does not leak. Other brands claim that it will not leak but found out the hard way that you must one thing or another to keep it from leaking. A grade schooler does not think about making sure the seal is on properly of that you must press the a spout down firmly. This Klean Kanteen is a simple twist to pop up the drinking straw and twist to close. Easy, simple and leak proof. No more wet homework papers......

This water bottle is easy to carry and I love the color, but it leaks heavily from the lid when it’s shut, and the inner straw is not secure. It was on its side in my bag, and when I went to pick it up, the bottle was empty and all my bag contents were soaked through. For the price I’m disappointed and will not buy this type of water bottle again.

Nice design and easy to use, though built-in straw sometimes doesn't snap up when twisting the top to use. Otherwise, very nice and ergonomically pleasing to hold.

I love my Keen Sandals because they are very comfortable! I have been wearing them when the weather permits and everyone has complimented on the way they look! I had a previous pair a long time ago and they lasted but I just wanted a new pair for this Summer! They are expensive but are very worthwhile! I recommend them 100%!

Was looking for a generous-but-not-too-big/heavy water bottle with a convenient carry-handle. This one was on sale and fit all of my criteria. (Including not being ugly, which counts for my tastes.) The built-in straw is easy to detach and clean, and it's suited my needs perfectly for travel and for everyday use.
