KOR ONE BPA Free Clear Reusable Water Bottle I 750mL I 25 Oz I Safe & Non-Toxic I Sustainable & Eco-Friendly I Leak Proof I One Click Cap w/ Handle I Wide Mouth I Great for Travel & Workouts

I have been an avid outdoors enthusiast for well over 25 years so I have had my fair share of water bottles. Sigg, Nalgene, Camelbak, Kleen Kanteen, REI, Eddie Bauer Etc.. I have had bottles from all of them. In fact I dont think there is a design or a company out there that I haven't tried. With that being said I ran across a KOR One bottle at my local racquetball club. I was immediately impressed by the design and since I was looking to buy a new bottle anyways, I decided to order one.All I can say is WOW, just wow. What an absolutely brilliant design. It opens up with a push of a button and closes up just as fast. Its so easy to open you can literally do it with one hand. It has two handles at the top which makes it extremely easy to carry. The handles also make it extremely easy to attach to a bag or backpack. The KOR ONE is made from Eastman Tritan co-polyester, a groundbreaking new plastic that has extremely high clarity, is extremely durable, and is bisphenol-A (BPA) free.The total capacity of the KOR ONE is 750ml which is imo the absolute perfect size for a water bottle. Its not so large that it becomes a pain to carry and at the same time its not too small thus unable to hold enough fluid. For those who are not very good with measurements, most bottled drinks that are available at the store are usually 16 ounces which is equal to 473ml. That means with a 750ml size, the KOR ONE is able to hold 25 ounces which is the equivalent to roughly 1.5 bottled drinks. Again, imo this is just the perfect size for a water bottle.My single favorite aspect to these water bottles is the diameter and shape of the bottle opening. Your bottom lip fits the shape of the opening perfectly. I swear it literally feels like they took some sort of mold of my mouth and created the opening of this bottle specifically for me. This is not an exaggeration, the overall comfort and fit really is that good. Its absolutely perfect as its wide enough to be able to do some serious chugging yet not so wide that it winds up on your face and shirt. In all honesty its the best water bottle opening I have ever seen. In fact, none of the other water bottles I have tried can even begin to compete with KOR ONE in this regard. Of course it would be criminal of me not to mention how amazing these bottles look. IMO they are easily the best looking water bottles ever designed. Of course how a bottle looks is not nearly as important as how well it functions however when you get a bottle that functions this well and at the same time looks this good....well, lets just say its a huge bonus!!These bottles also have some exclusive features. First they have what are called Kor Stones, which are disc-shaped tokens that have an inspirational message on them. They fit into the lid of your bottle so you see it every time you open up your bottle and take a drink. They are supposed to provide you with a little bit of inspiration each time you drink. Of course you could easily create your own tokens and put whatever you want on them be it graphics or even your name and phone number in case you lose your bottle. You can also buy something called a Yoli Blast Cap. Its a small cap that also fits into the lid of the bottle. Its basically a flavored vitamins and nutrients packet. Simply break it open at any time and your plain water is immediately transformed into a flavored vitamin water. I personal think this is a very cool idea, unfortunately the blast caps are pretty expensive so I have chosen not to use this feature, at least not yet. Hopefully the Blast Caps will come down in price as more and more people begin to use them as I really do think its an outstanding idea especially for people who take their bottles to the gym. I would definitely use such a feature if the price was right.I have now been using my KOR One for around 5 months and the more I use it the more I have come to appreciate it. In fact, I now have 4 of them in total. I keep different drinks in each one and keep them stored in my fridge. In the morning I simply grab whichever one I am in the mood for and off I go.The bottom line - The KOR ONE is hands down my single favorite water bottle in existence. Again I have pretty much tried every brand and bottle design in existence and imo none of them can match what the KOR ONE gives you. If your looking for a new water bottle then you owe it to yourself to give these bottles a try. Yes, they really are that good.5 Stars!!

First off, I have to say that the bottle itself is great. It's stylish and a lot better looking to carry around than an ordinary water bottle, if you're into that sort of thing, I'm not, but it looks awesome sitting on my desk.The rolled lip makes the bottle very comfortable to drink from and the ergonomic shape makes it very comfortable to hold. It's size won't allow you to put it in any conventional cup holder, but thanks to the locking mechanism and the rubber O-ring on the inside of the lid, your drink, whether it be water or any other kind of cold liquid, is not going anywhere even if the bottle rolls around a bit. The wide-ish mouth also allows you to stick most sized ice cubes in to give your drink that extra freshness.Now, while I do think the bottle is awesome, I do have a couple... not really cons, but things I wasn't really too chuffed about. First off, and sort of unrelated to the bottle itself, the packaging. Amazon didn't do a very good job with the packaging on the product like Kor Water would have done if I bought it direct. The bottle itself is supposed to have a nice polished look and for the most part it does. But because they didn't wrap it in some kind of bubble wrap, the inside of the box did scuff the bottle up in some places. Luckily though, the bottle is dark enough that it's not easily visible at first glance. If you were to buy the ice blue color though, this would definitely be worth the time it would take to send it back.Finally, and like it says in the title of my review. Cobalt Blue isn't actually blue. I've scoured the Kor Water website to find the one that the bottle I received actually looks like, but they don't sell a purple-ish one. So I'm not really sure how they got their image of the bottle looking so blue, but what you get with this one is not like that. From up close the bottle that I have is distinctly purple, from a distance and under certain lighting conditions it does have a blue haze to it.Other than the mentioned issues though, this bottle is a really convenient and slick looking bottle as far as bottles go. And... purple with a hint of actual blue isn't that bad.Update: I was just trying to upload a couple pictures of this, but I'm finding out that through some optical allusion or the material that the bottle is made of itself... it looks like a true blue from behind the lens. I'll try my best to capture its true color and upload a good visual representation of the bottle that you would see.

Let's be real: This is kind of spendy for a water bottle. Or a "hydration vessel" as I think they call it.Either way, I used a gift card, so I don't even feel bad about it. It's a nice water bottle, the closure fits well, a friend is making snarky "stones" for me to put in the top instead of the inspiring drivel they decide to print (they're pieces of paper, by the way).It seems to be pretty sturdy. I haven't dropped it on hardwood or concrete yet, though the metallic finish is a little easier to scratch than I would like.It's BPA free so my water is free from nad shriveling contaminates, which I enjoy. The water does taste fresher than most other water bottles I've used, especially after sitting for some time. I left it for 3 days in my car and the water tasted fine. I am what one would call an "advanced drinker", and I have yet to put alcohol in it. As much as I like a stiff drink, I don't want to smell it for eternity.Tl;dr - If it's good enough for Tony Stark, it's good enough for you.
