Question: how well does it keep liquids hot?
Document: Sending them both back tomorrow. They are not made as well, you can tell by the hollow sound they make when you tap on them (which doesn't bother me if it would keep liquids nice and cold like the old ones). I have bragged about these water bottles so much, you would think I owned stock in the company or something. Contigo, you need to fix this issue!
It keep liquids cool or warm for a day, way better than anyone else. The snap ring on the lid is actually pretty useful, which surprised me. However, I expect I will break it before the year is out, as I am rough on these items. The bottom rubber ring is glued on in addition to being formed for the bottom.
It's great! I've had it about 9 months now. It had survived being forgotten on the top of my car twice, and dropped outside on pavement. While there are a few dings and scratches, they aren't as noticeable as you might think. It def does keep my water insulated as well. I use it every day and will keep using it as long as it will survive. I only wish I would have purchased the 32 oz version of this, if there was one....
This is made very well. I like how easy it is to drink from, no more unscrewing a top etc.I am disappointed it did not keep my water very cold. I put ice and water in it at 2AMwoke at 10AM my water cool. It does not keep your water (beverage) cold for 20 hours as advertised.The water bottle I had before this kept my water cold but couldn't find a good deal so Igot this because of the sale. I prefer my gear bottle for coldness.
I have several other stainless steel water bottles: a classic Sigg, a wide-mouthed insulated Klean Kanteen, and a generic stainless steel bottle from Target. This Contigo is by far my favorite. It really does keep water cool all day. I took it to the zoo on a hot day and it was still cool after many hours.
I like to keep water in the car, but by the end of a hot day, water in a plastic bottle will be warm enough to steep tea. I've also heard that the plastic can contaminate the water if it gets too hot. This bottle keeps the water inside cool even when the exterior is almost too hot to touch. The water isn't going to stay cold, but it's definitely cool, even after sitting in the car for several days and with the sun beating directly on it for hours.
I have bought several of the previous models (Auto seal West Loop) for my family and for many gifts. Everyone loves them! The wide mouth makes for easy cleaning but the very best thing about them is that they keep their contents so very cold, even in a hot car. Recently I lost mine and so I decided I would order another plus one for a friend. I couldn't find that exact design (except in the 16 ounce size) so I ordered this new design.
Cleans easily in a dishwasher and the insulation works amazingly well. Ice cold water at 7am is still ice cold 8 hours later. Can't beat it.
we love the size and our icy cold water stay cold for a very long time. We left it icy water overnight and the next morning, ice is gone, but the water is still cool. The cap hook design is not the best and our biggest complain is the leaking! !..it leaked through the sides as well as through the spout
I love my Contigo! I love the fact that it is spill and leak proof. I was disappointed that it is only for cold liquids. I thought it would be for both, but the inner paperwork states only for cold. Tip: press the open button away from your face. Even though I am only using cold water, it spurts in my face if I press the open button close to my face. I have been squirted in the eye several times.
Answer: I have the West Loop and it will keep things cold or warm for about 3-4 hours as it transitions to room temp.  Good quality products!
