Klean KanteenTKWide Insulated Water Bottle with Twist Cap - Reusable Travel Water Bottle with Stainless Steel Straw - Perfect for Sports & the Office - Black, 20 oz

Good product

The twist top does not leak. In fact, it is airtight so be careful opening it on the plane, it will splash you when it decompresses. The handle is comfortable to hold, and I love the feel of the soft silicone (top part) and durability of the stainless steel (bottom part) straw. It fits in my cupholders. The wide mouth is easy to clean. The top lip is comfortable to sip out of when the top is off. There are other interchangeable lids of different types. It keeps my water cold all day easily. Sometimes multiple days. I honestly can't think of anything that could improve it.

This bottle is great! It keeps things nice and cold and the straw works well. It's easy to clean and the wide mouth actually allows our fridge to dump ice into it without it going all over the floor. It also feels really sturdy and I feel like it will last a long time. The only time I had it leak was on an airplane when the pressure changed, which is understandable. All in all its become my primary drinking bottle.

Truly a great insulated water bottle. It’s only weakness is a plane ride in which it will leak all over the bag or wherever you have it stored due to the pressure change.

I have purchased a lot of water bottles in my search for the right size ( holds enough water, fits normal vehicle cup holders, fits in water bottle pocket on my backpacks). I’ve gone through all the major brands and this is by far my favorite. The lid/ straw is a bit annoying to disassemble for cleaning but otherwise it is awesome. Keeps water cold all day easily without ice.

This has been a big upgrade from the standard screw-top reusable bottles that I'd been taking in the car. For hiking, there's nothing wrong with a good ol' Nalgene, but tipping the bottle back doesn't really mesh well with driving. Much better to have this in the cupholder. Same goes for working - I'm drinking more water now that I've started using this bottle at my desk.

Product is not very easy to use. The twist function is very stiff and difficult to work. It’s hard to twist the straw down and “lock” it into the closed position. Disappointing given the amount it costs.

These water bottles are amazing! Turn and slide to expose the straw… No spilling when you go over bumps in the car. Fits nicely in any beverage holder.
