First water bottle I've owned and I like it.  It stays cold for ages. I fill it at 7am and it's still cold by the time I get off work at 5pm, but my only problem was specifically getting white.  (Also, The first one I got had a small dent and the paint was already chipping, but it was no problem rma'ing it was so easy) With it being white it is easily marked up. I would recommend black or silver.

Update: I had a very tiny spot of rust form at the bottom of the flask. This company is amazing for its warranty. They replaced it with no hassle. Easily 5 star customer service.

I purchased the water bottle for my wife a couple of days ago. She plans to use it at work, as well as taking it on trips. It does keep the water cold for a long time, probably for at least the entire day. It is a cool stylish looking stainless water bottle, with the painted finish and stainless top and bottom. It is kind of heavy to carry if you are hiking a few miles without a backpack, especially compared to a plastic water bottle. The great insulating quality makes it a little fat to carry in your hand for a long time however with the extended time that your beverage remains cold, it is well worth it. A mesh or drawstring bag would help alleviate the weight problem I think. My wife really likes this water bottle, and we would buy it again if we lost this one.

The only downside is the screw on lid. However that's just a personal preference for me. I wish there was a spout type lid or straw type lid they offered that fit this water bottle. One things for sure, this water bottle has allowed me to throw away every other plastic water bottle I owned. Who needs plastic when I have this stainless steel one, right.

After reading the reviews of this and other water bottles I tried this one.  Great bottle, first off it really does keep beverages cold, not everything does what it says.  The opening is big enough for ice cubes (ice cube maker types) to fit in.  The ice will last hours even with the bottle in the sun.  The flip-top lid is a great convenience, as is the latch so you don't accidentally open it.  Also has a rubber covering so it will not slip out of your hand.  Little things that really make with a nice bottle to use.

It also leaves no condensation so is great to use in the car.  And it fits the cup holders, can't say that for other bottles.

The only negatives I have are:  first, the cover and spout under it heat up in the sun.  I use this on my tractor cutting our grass and trails and it takes hours to do and there is no way to shield the thermos.  Just kind of weird to put your lips to a spout that is hot and have ice water come out.  Maybe a lighter color would have helped.  Second, it is kind of small when you may be drinking for hours.

I have heard this bottle criticized because it doesn't have a hydration meter.  To keep this simple, if its an 18 ounce bottle and you drink half you drank 9 ounces, if you drank a third you drank 6.  I guess if you're a competitive athlete, OK you need a meter, but for us common folk we need a bottle that keeps liquid cold, doesn't sweat, doesn't cost a fortune and is easy to use.

Keeps cold for around 10 hours. Not as cumbersome as other big water bottle I've had. Strew is almost the perfect length.
Would have gotten 5 stars but there were 2 problems. 1. Doesn't fit in cup holders. 2. If the lid is not torqued down there isn't enough threading to keep it on if it falls or picked up, by the lid handle, while it's full.

This water bottle is quite nice. It's very large, which has its perks and drawbacks, but it holds a lot of water which is what I wanted. As some other reviews warn about, it does not fit in my cup holder so I have to put it in the seat next to me on a drive. Also the cap is not entirely easy to "snap" into the back of the lid so I often don't bother, however, it is easy to hold the cap back with my finger with the same hand as I'm holding it.

I am very picky about my water bottles, so it definitely takes a lot for a new bottle to impress me. The Coldest Water bottle has done that. I have not tested the accuracy of the product name ("The Coldest"), but as far as I'm concerned, it has done its job and done it well. First, it is sturdy and not cheap feeling. It is too early yet to tell whether the outside of the bottle will hold up to my daily usage, so I will try to post an update later. As for keeping my water cold? Yes, I'm happy to report it has done that. I fill it with ice and cool water in the morning and continue topping it off throughout the day. The next morning, there is still ice in there and it's still pretty cold. The top that comes with it feels sturdy, but I wanted a more convenient way to drink my water; so I purchased the separate straw top (a little pricey at $9.99 in my opinion). I do like the straw top as it makes it much easier to drink from a reclined position. I hope this bottle will hold up the way my Zojirushis and Kleen Kanteens have and I look forward to testing it under the blazing heat of a good old California summer!

I have gotten my money worth for this Klean Kanteen. I ordered the 32 oz so that I could stop using water bottles and reusing water bottles at that. The water tastes fine and it keeps it cold. That might be my only issue as i prefer room temperature water. So, water from a water fountain stays pretty cool longer than I would like it to. I've learned if I take the cap off and let it sit the water will get a little warmer. Again glad I made this purchase.

A great purchase. I use it for a water bottle, and it keeps ice for a little longer than 24 hours. That is plenty for me.  Holds a lot of water. I bought a sport cap to go with it and it is perfect. I like the swing lock if I am going to have it in a bag or something because I know it won't leak, but the sport cap is easier to drink out of.

Great bottle! Got it so I didn't have to keep hitting the store to get new plastic ones. They always get nasty after a week or so. This thing keeps my water cold for a long time.

The size adds its own issues though. The first time I filled it up, i was taking it out to my car and bobbled it because it is so heavy and it hit the pavement. Cracked the cap and put a big dent in the stainless steel! Still worked fine though. I bought a new cap from Hydro Flask for $3. Turns out RIE sells them too. It wasn't the last time I dropped it either. No matter the stainless holds up good, a few dents and scuffs are to be expected. I just wish there was a handle or rubber bumper strap to go around it for safety.

I accidentally left it in a hotel on a road trip and had to stop to get a new one! I recommend buying the flip cap though. It is a little hard to drink out of the extremely wide lid on the go without spilling some.

I bought this bottle as an alternative to the much more expensive Hydro Flask, after reading a few customer reviews stating that it kept water cold for 24+ hours. I'm extremely happy with the bottle after over a month of use. It keeps water cold for around 24-36 hours after I put ice into it. The build quality of the bottle is very good, and the only time it's shown any wear is when I dropped it on my driveway and a little chip of the black exterior broke off.

The only complaint I had with my bottle is the quality of the strap on the lid. Under normal use, the strap broke in half after maybe two weeks of daily use. I had a follow-up e-mail from Klear asking how I liked the product, so I responded to them asking about a possible replacement. They responded very quickly and let me know that they were disappointed in their original supplier and have cut them out. They are now sending me a replacement lid without a strap, which was my preference.

Love it. The bottle feels great to hold. My water stays cold for hours  even in my hot car.

I wanted a new, bigger water bottle to replace my 24 oz. sport bottle. A friend recommended Hydro Flasks, I did a little research, and ultimately got a great warehouse deal here on Amazon!

I purchased it used so when I unboxed it, there were two small but prominent dents and some scratches. Nothing too bad and it didn't seem to alter the insulation.

I've had it for about two and a half months and I think it works great. I drink a lot of water so the 40 oz. was an ideal size. Great color and I even added my own stickers to give it some personality. I try to clean the inside out with a bottle brush about once a week, so I haven't smelled any foul odors.

The insulation is no joke, man. I've left it in my hot car multiple occasions for hours. Still cold as when I filled it up. For the best results I usually fill it with water that is already cold and a few ice cubes. If it's just room-temperature water the ice melts way faster so this might not be convenient for some. I have not tested it for hot liquids in a cold environment yet, but hopefully I will get the opportunity soon.

I'm somewhat skeptical about the durability claims, so that's why I'm not giving it a full 5-Star. I dropped it in a parking lot and made a new dent in it. It wasn't a far height (I stand about six-foot-two and I dropped it at about where my waist is) so I was a little disappointed. Maybe it just hit a bad angle, but I haven't dropped it since then because I don't want to add any more dents.

Additionally, the company does a great 5% Back program that allows you to donate part of your purchase towards a charity of your choice (as of right now, their charities are: Adopt-A-Classroom, American Cancer Society, American Red Cross, Charity: Water, Fair Trade USA, Habitat for Humanity, Kids in the Game, Leave No Trace, Special Olympics, Surfrider Foundation, United Way, and WWF).

Overall, I'm happy with my purchase. I hope I don't bust it up more.

I ordered the 25 oz Sunset Orange bottle.
I really like the bottle, Like the color, Like the design. Everything is great about this bottle.
I do not put any hot liquids in here so I can not vouch for how long it stays hot.

But it is currently Summer In Ohio.
I can put Ice/water in this thing, Leave it in my hot car for two days and come back and there is still Ice and water on the inside.
So this thing keeps liquids cold af. Which is good and bad. ive figured out a happy medium to get lots of water and little ice, and still keep it cold.
First week I had this I was putting too much Ice inside and the ice wouldn't melt.

I've had 0 paint chips inside. the bottle but it is starting to come off where the lid screws and makes contact with the bottle. But anyone with a brain will realize this will happen. Can see it in the picture.

be careful dropping it. Ive done it a few times and got some very small dents. It is a Vacuum insulated bottle so a major drop could render this thing useless.

Only reason I am rating 4/5 stars is the nozzle or top of the bottle is kind of small(Which is nice to drink from) But It is hard to fit ice cubes inside. Luckily where I work(amazon lol) We have crushed ice.

It is also Leak proof.

At 24 ounces this water bottle is a good size for me, and it is slim enough to fit snugly into the cup holders on my treadmill (a larger water bottle I own does not). The cap seems well made and is fairly heavy, and the straw screws into the cap and can be removed for washing. The drinking spout folds down under a cover, which clicks shut and can be locked, too, to prevent accidentally opening the bottle.

I think it's good sanitation that the drinking spout is covered except when you want to use it. The only odd thing is that the spout is kind of wide and it seems odd to drink from. That's really the only reason I gave the product four stars because of the awkwardness, but I think that will be something I will get used to. It's just much wider than a straw. Also, it's a bit squishy so you might find yourself tempted to chew on it. So far I haven't done that, but I'm wondering how durable the clear mouthpiece will be. I actually had a hard time deciding between four and five stars; I'd give it 4.5 if I could.

The bottle is marked in ounces and milliliters and the straw sits so very near the bottom that you can get almost all of the water out of the container -- another feature my other water bottle did not have. The clip is sturdy and has a movable section that can be opened for clipping onto a belt. I also like that the top has a rubberized grip that makes it easy to open the bottle. In all, this product seems well made. It's BPA-free. Also, it doesn't seem willing to topple over when it's empty -- I'm sitting here tapping at the empty bottle and it rocks a bit and settles down. Sure, I can make it fall over, but that's not the point -- despite the heavy cap it doesn't behave as if it's top heavy, so I hope I won't have any waterbottle vs. the keyboard issues!

I wanted to give this product more stars. Don't get me wrong, I'm very happy with the water bottle. It keeps my water very cold for hours, has a mouth just wide enough to fill it with ice without hassle, and, despite being made of plastic, the screw-on top appears to be quite sturdy. I wouldn't advise letting the bottle take a tumble top-first, but it doesn't seem like it will snap off with daily use. Initially, I thought the straw was going to be too short, but that was just me failing to take into account the inch or so lost when the top is screwed down. My only complaint is that the top can leak if you don't close it tightly enough and the difference between "enough" and "not enough" can appear negligible. Now, on to the reason I knocked two stars off: the pouch. After only two days of use, I can already see an excess of loose and unraveling threads. The stitching that was meant to reinforce the strap has completely unraveled. The seams are already showing signs of wear-and-tear. I'll give the strap a month until it snaps. The pouch might last a bit longer. So overall, I'm happy with the water bottle, but disappointed with the sloppy stitching on the pouch. At least the material seems thick enough to cushion the bottle and prevent dents should it fall from a table or similar height.

*Edit* So my bottle took a nose dive from my desk and to my surprise, the plastic top survived the fall! The bad news is that the little tab on the mouthpiece that's supposed to help open and close it broke off. I now have a sharp edge on my mouthpiece I'm not happy about. Luckily, its absence doesn't affect my ability to open or close the bottle, so I do wonder why it was there in the first place.

I am one of those people that cannot drink and walk at the same time. So when I buy bottles, I am very particular with the mouth piece. I like the wide mouth for putting ice into, but not drinking out of. The sippy lid is great. Even though my water doesn't stay as cold as long as it would if I had the regular lid, it still works beautifully. Forgot to put it in my bag for the gym, and there was still unmelted ice in the container 14 hours later when I got home.

I have to note that while the bottle is leakproof, the lid portion isn't insulated. So when I have the bottle on its side, condensation will form on the black lid part. It's not the end of the world.
