NAK Fitness Quench Bottle Flip Top Lid 32oz. Double Wall Vacuum Insulated Water Bottle. Premium Grade Insulated Stainless Steel Water Bottle. BPA Free

I got mine a couple of days ago and I really like it. I work in an aircraft hangar that can get warm during the day and I needed something that had good capacity, kept my water cold and didn't sweat. This seems to work perfectly for that. It is a "noisy" bottle, though. The ice sloshing against the sides is surprisingly loud. It is a little large for my hand but using the ring on top it is leveraged well enough to make my grip on the bottle secure and make drinking easy.The only complaints that I have and the reason that I knocked off a star is that it arrived with two issues. The first is just a minor amount of cosmetic damage. The powder coating was rubbed off in two places at the bottom leaving bare metal. Looks like it came from the factory this way. The second can affect how it seals. The rubber ring in the lid was not properly installed in its recess when assembled and a loop of about 1/3 of the rubber was loose. When the lid was screwed onto the bottle, it pinched the seal and put a slight hole in one side. I pushed it back into place and it seals well enough for a knockover. But if it is left on it's side for a minute or two, water will start to seep out. Not a big deal but for the price of these things I would have rather had a bit more quality in it's assembly.Edit: 2 weeks later. I dropped off another star because the cap broke. The lip that you push up on to open the bottle snapped off. I can still open and use the bottle. The only real issue is if I flip the lid 180 and push it down on the other side of the cap in the stowed position. Since that lip is now gone, there is no way I can push up to flip the lid the other way and close the bottle without slipping something in there to pry it back up. Disappointing. I like the bottle. It keeps my ice water cold a long time. But the cap is certainly the weak point of this product.

Holy shiitake mushrooms. I've had this bottle less than 12 hours and I am simply amazed by this thing. 2 words. Louisiana summer. Its a whopping 115° outside and these "geothermal AC units don't produce enough cold air to keep even a house 1/4 of the size of mine cool enough to be bearable. So it gets around 80-85 degrees in my house and at work. So....not to be gross.... but I end up sweating. A lot. And then my water gets hot. And I really don't want to drink hot water when I feel like I'm boiling myself. Oh! And another thing. You can't drink the tap water here. Its brown. Soooo there goes me being able to dump the hot water out and refilling it from the tap at work that's semi (normal) room temperature. So....this destroys both. Its 3:30 in the morning and I still have ice in my bottle that I've been carrying around since around 3:45-4 pm. FULL ICE CUBES. And theres no outter bottle sweat that make my hands even sweatier and then the bottle goes flying across the room. Nope. Just cool grippy powder coating and freezing cold water inside that tastes like liquid gold. Yeah I could gripe about the small drinking hole.....but I actually kind of like it. I always end up drinking my water too fast and choking and spewing water everywhere lol not with this one. I absolutely ADORE this water bottle and am probably going to end up getting another for my husband (or for me when this one is in the dishwasher) but this is by far the best water bottle I have ever purchased. Very impressed with the design and functionality. I love the loop for a carabiner to hook it on your bag. It's also rubberized on the inside of the hook so it's easy to hold on to when your hiking etc and your hands are sweaty. There really is not one aspect they didn't execute well. Everything is very thought out well. I know y'all are probably saying by now.....cmon lady. Its a container. To hold water. But that's just it. It's not JUST a water bottle. It's an exceptionally well thought out water bottle that does it's intended job exceptionally well.

UPDATE: Just after posting the review below, the company emailed me and said they were sorry for the leak and mailed me a new lid. The new lid works great! Now I can throw this bottle in my bag and not worry about anything happening to it, or anything else in my bag. Everything is dry.I prefer my drinks lukewarm (yes, I'm that guy), so I don't care so much about how well my water bottles insulate; even so, this bottle works well at keeping drinks cold. I usually throw my water bottle in my schoolbag (my bag doesn't have one of those mesh bottle holders), so I needed something that could handle my heavy textbooks occasionally being thrown onto it. It's SUPER sturdy, so it could handle that - no problem. But, during the first day I used it, I noticed the flip top lid on my bottle leaks a little. That's not good for all the books and papers I keep in my bag, so I immediately took it out. I even tested it by squeezing the lid shut as hard as I could and gently tilting the bottle sideways to see if water would still come out. Alas, it still came out. Just a small trickle mind you. Nothing crazy, but I've had enough bad experiences over the years of getting books, etc. wet that I just don't risk anything anymore. Now, I just keep the bottle on my desk where I do my homework. It's kind of a bummer, since my sole purpose in buying it was to replace my store-bought Smart Water bottle, but oh well. It looks nice on my desk!
