This water bottle keeps the water cold for many hours.

It does not sweat & has not had any broken parts after 3 months of use.

I have been looking for a new sports water bottle, and when I saw the picture of this bottle and the number of high reviews, I HAD to have it!
The first thing I noticed is how cute the gift case looked. I'm not one to make a fuss about packaging, but this is worth mentioning, because it was very sleek.
This water bottle is gorgeous! The color is a deep pink and it's very shiny. I also like that the bottle is curved.
Everyone knows that a sports bottle can look great on the outside, but the most important thing is that it works and meets my needs.
I am constantly drinking water and one benefit is that this bottle holds more water than my others, so I don't have to constantly worry about filling it up. Summer is right around the corner and I'm going to be drinking more water than usual, so this will help me to keep hydrated.
It's made from quality stainless steel so there's no worries about having an after smell. It's lightweight but still sturdy and easy to clean.
I've already had friends asking about how they could get one of their own!
I have received a discount on this product in exchange for my honest & unbiased review.

I just got mine this last week. It's great. The high points of it are:

1) Great ability to keep drinks cold.

2) Fits in a tote bag, cup holder.

3) Easy to drink out of with out blocking your view of the road ( while walking) or having to open the cup up to drink out of.

4) For once no spill means NO SPILL!!!

The things that I don't like:

NOTHING!! This thing rocks! I will probaly get a bigger one for me and some more of this size for the kids for the summer. But honestly if you want something that will help you increase the fluids while monitering them this water bottle is really great.

I used to think that all water bottles were made the same, until I tried this one. It's not just that it keeps the water cool and that it matches the color of your bike, it is the technology of the hole that makes water flow out in a perfect stream of freshness. Water tastes way better than with other waterbottles.

On the downside, it is made out of plastic and it has places that ar hard to reach, so it won't last forever. I replace mine every 4-6 months

First off, this bottle is amazing. I'm a college student with at least an hour of walking between classes per day in 90 degree weather and this bottle has been extremely helpful. I'm able to easily keep hydrated during the day and easily refill the bottle. The material on the outside of the bottle is nice because it makes the bottle easier to grip to. The strap is really useful for when i need to keep my bottle in my hand, hanging on my wrist or clipped onto my backpack using a carabiner. The top has a spring that allows the bottle to be easily used one handed even for its size, all you have to do is press the button on the top to immediately start drinking. The lock is used for keeping the bottle from opening and it is very useful when I have to put the bottle in my bag. The bottle is sealed well and has never leaked before in my backpack. The wide opening top is convenient when I have to fill up my water bottle at water fountains. The wide drinking water opening has allowed me to easily drink water and chug down 16-18 oz of water without stop because of the air hole at the top of the bottle (which is also sealed when the top is closed!). All you have to do to drink water is put the bottle at an angle and water pours out (no sucking involved!) I have yet to drop the bottle because of the outside material and strap so I can't really comment on that. The aesthetics of the bottle are simple but nice looking. The quote "Fortune favors the brave" and the logo are accurately shown in the picture and makes the bottle look really attractive for such a simple design. I will recommend the bottle to anyone looking for a large premium bottle because this bottle is definitely worth the $20 price tag and has been a huge help for me during the summer

I bought a few water bottles from amazon but this is my favorite! Seems very durable. The pout doesn't require you having to manipulate it to open it. So you drink on this even your hands are somewhat dirty!

I bought the Boroux bottles to start using borosilicate glass water bottles instead of plastic Nalgene bottles.  Although those Tritan bottles are BPA free, there was still a mild plastic taste to the water and drinking out of them was not my favorite.  I was quite pleased with the Boroux bottles, although like many others have mentioned, the silicone seal almost always comes off when opening a cold bottle for the first time.  I found my water tasted fresh and clean, and was easy to drink out of so I found myself drinking more water throughout the day.  I wanted more bottles, but didn't want to pay the higher price for Boroux, so I went with this Aquasana six pack.  It's six bottles for less than the cost of two Boroux bottles!

Both are crystal clear with no visible waves or bubbles in the glass whatsoever.  The Aquasana bottle is slightly taller and as a result holds 50ml more than the Boroux.  The glass thickness of the Boroux is more stout so it may take impacts slightly better than the Aquasana, but after using them more, I do not feel this is too much of a negative point.  The available silicone sleeves for the Aquasana are a great option. The Boroux bottle has a wide mouth so it's easier for putting other things besides liquids into the bottle (ice cubes, powders, and cleaning tools).  While both bottles are easy to drink from, I find the smaller opening of the Aquasana to be more preferable than the wider Boroux mouth.  The seals of the Aquasana bottle have stayed in place throughout all my use of them so far, but the Boroux seals tend to come out all the time, such as when filled at room temperature then placed in the fridge to cool.

Personally, I see uses to having both and I'm glad bought both to have the options.  For the price, the Aquasana bottles cannot be beat.  I definitely plan on buying more in the future.

My mom and I absolutely love this water bottle. It really gives the water a better taste that doesn't seem like it's been chemically treated. My mom also liked using it because she has well water. It filtered out all of the impurities from her water and made it taste much better. I really like the design and look of this bottle as well. It's easy to clean. And the filter should last a little while since I mainly use it when I'm going out and want to take something to drink with me. The replacement filtes are pretty cheap too which is another plus. The clip is also nice for when I take walks, but I wish it was a little better made. It can probably be easily replaced with one of my own though. I spend a fortune in water bottles that I end up having to recycle in a bin that is taking up more space in my kitchen. Maybe if I get a few more of these, I can get that space back by not having to by water bottles anymore.

I had lost my old Contigo water bottles, so I had to buy them again because these bottles are the best water bottles I have ever had. The size is just right at 3 cups so it is not so heavy when hiking or biking, but large enough to keep you hydrated for a long period of time. The push button open mechanism is a great feature that has NEVER spilled for me. The straw hole is very large, so you don't have to suck for a long period of time for a small amount of water to go through. Great design. The straw can be separated from the top of the bottle for easy cleaning as well.

I've tried a lot of different water bottles and this one is by far the best that I've found.  It comes along with me wherever I go.  Right away I noticed the mouth was wide enough to easily add ice cubes from the ice maker.  I can fill it with about 50% ice and let it sit out in the desert heat (110F) and the water is still cold after several hours.  The fact that it came with multiple straws let's me know that Hydracentials cares about making their customers happy.

As for durability, I haven't owned the 25 oz version for too long but I've owned the older (smaller) design for a while and it has taken quite a beating from rock climbing, hiking, coaching soccer, kids and it still works perfectly.

This is a great water bottle.  I like it so much better than the straw model.  It's fantastic that the container is closed until I pick it up to drink it.  That has worked well as I garden --- no worries that hornets have made their way into my drink.

There's something else about this container.  Because of the design, it is easier to drink more water than even out of a glass.  During our hot summer, I've found it very useful to help me drink enough water.  My head is tilted back more than when I drink out of glass which opens my throat somehow.  This may sound weird, I know.  It has been so beneficial for me.  I need to drink more water and this has made it easy.

I'm thinking of buying two more -- one to keep in my car (the original reason I bought it), one to keep by my bed and another for the garden.

My first order was for my sister.  I got her two different types of water bottles for her birthday and this one was by far her favorite, so I ordered one for myself.  It has literally kept water ice cold for hours in a car sitting in the hot the Florida sun, and then overnight at home. Plus it doesn't sweat.  I have gotten to the point I make my ice water up the night before my run so I can just head out the door with one less thing to do, and the ice cubes are still there in the morning waiting for me to come back from my run.  The cap flips open with the push of the button at the front.  There is a little lock you can put in place so that the top won't pop open when you don't want it to. I find with the Thermos I am drinking more water simply because it is so convenient, doesn't sweat and keeps water super cold just how I like.  My husband liked mine so much and was trying to steal it, so I bought him one too and he carries it to work everyday.  My 6 and 9 year old have now asked for their own because they like how cold the water is.  Prior to this we all had those special BPA free plastic water bottles but here in Florida the ice melted in 20 minutes and they sweated so much we would have to wrap them in paper towels.  Now that soccer season is getting ready to start we won't have to worry about or son's water going warm before his game is over.  Get this water bottle, you will be so happy you did.

I bought this to test vs.a couple of other water filtration bottles so that my son and I could bring the perfect water filtration bottles to Boy Scout summer camp.  We are both pretty picky about our water.  The water from the Bobble tastes great and the water flow is pretty good because you can squeeze the sides of the bottle to help it come out faster.  I decided to buy a second bottle because it works so well.  This 34 oz bottle seems a little big to me, so I bought the 24 oz version for myself.  But my son loves the bigger one and wouldn't give it up anyway.  I love that they come in so many colors.  I also like that this version has an attached cap, while some do not.  I know my son would lose the cap if it were not attached.

This is my third Lifefactory water bottle, and the best one so far.

The Lifefactory is very nicely made from quality materials that are well finished.  The thick glass bottle is surrounded by a silicone sleeve for protection and grip.  Be aware though, it will only protect the glass from minor bumps and bruises.  One of my older Lifefactory glass bottles broke after I dropped it onto a vinyl floor from about 5 feet up, so you still have to treat glass like glass.  With that said, I've used various Lifefactory bottles for years and that was the first one that broke.

The drinking spout on this bottle is improved from earlier versions that I have had.  The opening is much larger and easier to drink from.  The top is simple to open and close with one hand and there was no leakage.  When closed the top snaps shut firmly.  There is a small built in handle attached to the top to make the bottle easier to carry.

Since the bottle is glass it gives the beverages inside absolutely no aftertaste, does not stain or scratch, and cleans up very easily.  Indeed I've cleaned it in my dishwasher and it came out perfectly.  It's also easy to clean by hand, but you'll need a bottle brush.  If need be you can remove the silicone sleeve to clean behind it, but it takes some time and finesse to get it off and back on.

The bottle hold 16 oz of fluids, so a decent amount, but not so much that the bottle is too big to slip into a lunchbox, backpack, or cup-holder.

All in all... a wonderful water bottle.

It has been surprisingly frustrating to find a good water bottle.  Been using the plain ol' free "sport top" bottles from bottled water for years, but finally decided to try something claiming to be safe.  This is the third try - first, was a Rubbermaid bottle that looked nice, but was too inflexible to actually squeeze out any water.  Then came the "fuel belt", that looks really cool but leaks like crazy.  At first, this third try leaked too, but I found it doesn't leak if I don't use the loop that goes under the lid (said loop holds the handle onto the bottle, can probably stretch it over the outside of the lid instead of under it)  This one has been working OK for a month now, so I'll call it successful!

When I lost my old trusty wide mouth Nalgene of 8 years last summer, I knew exactly what I was looking for in a new bottle.
Bright orange color (favorite color...not important), durable, straw sip mechanism, NO bite valve, transparent enough to see water line, and clip on lid.

I looked through so many bottles...the top two flip straw bottles at the time were Camelbak and Nathan.  The Camelbaks are nice. Many of my friends have them.  The only problem is how easily mold can grow in the bite valve.  So I got the Nathan instead, and couldn't be more satisfied.

Unlike many other customers, I do not have problems with my bottle squirting when I flip the straw out, or water pooling anywhere.  Sometimes the lid leaks a little if water collected at the base of the mouth piece, but I really haven't experienced any other problems with this product.

The thing I like most about flip straw bottles is being able to drink while in motion!

One little thing that I didn't expect is that the outer layer of film on the bottle that gives the bottle a "foggy" transparent look instead of clear transparency is starting to flake off little by little.  So my bottle looks a bit like a healing sunburn right now.  But it functions well, which is what matters.

For the price and quality, this can't be beat. It does what it says-it doesn't leak, hasn't broken despite dropping it multiple times, saves money on water bottles and reduces landfill waste, and has a good flow - especially compared to the CamelBak sipper. You do have to press the button down the entire time you drink, but that's where your hand would be putting pressure on the bottle anyway. The size is great and fits in most cup holders, including my car's abnormally small cup holders, and the clip is very handy for outdoor excursions. You drink out of this differently than most water bottles. Instead of rounding your lips, you flange them out a bit.

What I don't like is that for females, if you have lipstick or lipgloss (or even chapstick) on it tends to kind of "collect" on the seal-but is easy to wipe or wash off. I wouldn't recommend putting anything but water in here, because cleaning it after any sugar-based drinks would be more of a challenge. Also, this is a tad more obvious, but it isn't good for sodas because it's sealed so the pressure would build up.

Overall, this is my favorite water bottle, especially for errands and outdoor adventures.

Update 3/2012: We have since gotten rid of all of our Camelbak water bottles. Both Contigo water bottles we purchased are still going strong, despite daily use and multiple droppings (oops). It is dishwasher safe on the top rack, but we live in an apartment with a small dishwasher that won't allow it to fit on the top rack, so I hand wash them. I love that I can toss this in my purse or bag and know it won't leak. If you use ice in this bottle and the condensation bugs you, this sleeve does fit this water bottle, but the bottle can still rotate in the sleeve so you have to align it when drinking-not a big deal, but worth noting: http://www.amazon.com/CamelBak-Liter-Insulated-Bottle-Carrier/dp/B0019DCDIO/ref=sr_1_1?ie=UTF8&qid=1363328055&sr=8-1&keywords=camelbak+sleeve.
