I really like it! Keeps things very cold. A bit big for my hand and I can taste a slight taste of metal. Over all good.

I've had this bottle for quite a while now.  I like my water really, really cold and this bottle does the trick.  I use it daily at work, and will find ice in it the next morning.  I purchased the metallic red color and it's very snazzy looking.  I haven't had any trouble with leaking or spills with this water bottle.

This bottle does what it says, and keeps drinks cold for a very long time. I made some instant Snapple in it and sat it on my desk without even putting the lid on, and came back to my room (which was around 90 degrees fahrenheit) over two hours later and it was still cold! I would definitely recommend this bottle to anyone that likes to drink cold water or the like.

I love it. It works great. I was just looking for something I can place next to my best to keep a cup of water cold, and so far it has worked great!

WOW...I haven't used it for hot things yet but for COLD things it has incredible insulation. It will keep cool drinks cool even in the direct 80 degree Sun! On average I can put my bev in with one ice cube and it lasts most of the day. Very happy!

I only like very cold water, and I have been trying to use less plastic, so I got a non-insulated Klean Kanteen awhile back. While that one sweats a lot and doesn't keep things cold for very long, this one doesn't sweat at all. I love it; I can fill it with ice water, close it up and sit it on my counter overnight, and there will still be ice in it in the morning. I worry that when I drop it, it will scuff pretty easily, but I have yet to let it slip out of my hands, so I can't say for certain on that. Also, the lid on this 20 oz. bottle is much easier to open than the loop lids on the smaller bottles. I recommend bigger ones for that reason. Overall, really great product.

Let's say 4.5 stars, I really like it, I get compliments on it, Iuse it a lot, I love that it's versitle by having the option to add ice, it fits more items than I assumed. I only have 2 small complaints, 1. it takes awhile to get cold/hot I would estimate (just a guess) 35min to get cold or hot, so that means if I turn it on by the time I get to the store or restaurant it is still warming or cooling and not yet ready. Now I will say my car turns off all electronics when the car is off, so if your car plugs stay turned on even when your car is not, then you may have more luck with it cooling/heating before you need it. My recommendation is to buy the wall AC to DC adapter so you can pre chill or heat the cooler before you need it. Also when you show up to a party you can just plug it in at the party otherwise it will slowly warm up when it is unplugged. 4th of July I cooled the case down then showed up to an outdoor pool party where it was 100 degrees out, after a couple hours the drinks inside were warming up so I dumped ice in it, which was not a problem, but if I had the adapter I couple have simply plugged it into the wall and not deal with ice. 2: the lid is hard to open, especially with one hand. Every now and then while trying to open the lid, the entire lid disconnects and falls off, this may be a way they insulate better, I've seen this design on some small fireproof safes.. but I'm not a fan of the lid.

Does what it's supposed to. Insulates very well and keeps things cold for a long time.

This works great.  I actually plugged it into a converter that plugs into my car that has an on/off switch so I never forget to turn it off.  It is great at keeping things warm and cold.  I do chill my drinks before I put them in and it keeps them cold for hours.  Sits right behind my seat, holds a 6 pack.  I love it as I am frequently out on rural back roads all day with no access to a store, so with this, I have my own store for my drinks, lunch, sandwiches, snacks.

This is a great bottle and keeps things so cold for a long period of time.  No sweating at all - can throw it in my bag and go!

I've only tried this with cold beverages so far, but it is quite amazing!  I can put ice cubes in it in the morning and my water stays cold, WITH ice cubes still in it, the whole day.

I really like it, I use it on my bike and you can freeze liquid in it about a third full then add more ice n liquid when you are ready to go. Stays cold for a few hours on a hot day.

It's a terrific container. Keeps your drink very cold or very warm for an extended time. Very durable just be very careful about dropping it on its cap end.
