KOR Nava BPA Free 650ml Filter Water Bottle, Black/Red, 650ml/Black/Red

I bought the red-and-black version and fell in love as soon as I unpacked it. I've had a growing pile of plastic bottles in my dorm room (much to my roommate's dismay) and decided enough was enough. After a few hours of comparing reviews, I settled on the CamelBak Groove...and this one, mostly by accident. Almost instantly, I made my decision, and I haven't regretted it for a second.The Tritan plastic is strong, feels durable, and has some weight behind it, which is more comforting for me personally than a flimsy or lighter plastic. Upon arrival I inspected the bottle for any defects - scratches, bubbles, loose adhesive, cracks - and found nothing more than a three-millimeter imperfection along the soft interior joint of the handle which was pretty astonishing. At the very least, I expected a scratch or two from manufacturing. I disassembled the bottle, inspected the straw and mouthpiece, and followed the instructions (which have probably become more clear-cut since other reviews, but just in case...soak the filter for 30 seconds and put it in rubber-side down).The seal works, which is nice. If you need help lining up the cap use the side guards as guides and don't just yank on the lid to close it. I held the bottle upside down for ten minutes while filled to capacity and couldn't find any leaks. The sweating was pretty average, but considering it's not insulated, I'm not surprised. It's not a thermos, and not designed to keep things hot or cold, or that would be a noted feature, right?Drinking from it takes some getting used to, but it really is comfortable on one's lips. I didn't detect any strange flavor, nor any of the typical plastic aftertaste of other bottles but I did notice a strange taste from the mouthpiece. It's very subtle, and I wouldn't have noticed it had some other reviews not pointed it out. It doesn't distract from the cleanliness of the water and, after a second or two, becomes completely unnoticeable. (It might be cool if there were flavored mouthpieces, but that's a pipe dream and I know it.)I wouldn't suggest slamming the bottle against the ground, since that would cause most things to break or be dislodged. That being said, simply dropping my bookbag from shoulder height on to asphalt hasn't seemed to cause any damage. I'd look to some other reviews if you want a greater look into just how durable this thing is.All in all, it's pretty perfect. The Nava holds water without leaking, even when turned upside-down. The button and locking mechanism are things I've always wanted in a water bottle and the filter, lovely design, and BPA-free plastic are all bonuses. It fits perfectly into my backpack's side pockets, and it fits into the trough lower-door trough in a car. It does not fit into a cup holder, but I don't mind - I'm used to riding either without an available cupholder or without cup holders in general. The filter works on dorm water (note: my dorm was built in the late 70's and hasn't had updated pipes since, and the water is pretty nasty) to give it a nice, clean taste, and cap is a cleverness unto itself. I no longer need to worry about losing a cap or having some easy-to-break lid hung on by a strap!Just push, sip, and seal. It's really that easy.(Plus: Now my roommate can't glare at me for leaving empty plastic bottles hidden in a pile on my half!)

Been meaning to drink more water lately and having a bottle with a filter definitely a good motivator to do so. Cap fits well and can be opened one handed, the top springs open and the mouth piece shoots up, can be easily closed with one hand and the filter works as it should. Feels good and made well, the rubber bottom is actually very useful so it doesn't slip about. Great for keeping at work and getting to drink a lot more water

So far, product has worked as expected. Went together easily and you can definitely notice the improvement in flavor as you drink the filtered water. Haven't dropped it yet so can't tell you how it'll hold up but the lid and carabiner-like handle (doesn't have a built in clip) are solid. It latches shut and when you press the red button, the lid pops back. When the lid is down, the mouth piece gets pressed down as well and cuts off the tube for a watertight seal. Only time it's leaked was when I didn't screw the lid on properly. If you rush, it's easy to cross thread it. The body itself has a hard plastic like feel on the transparent part but you can actually squeeze it. It's firm but at least you know that it'll give a little instead of cracking under pressure. Like advertised, water is pulled through the filter easily and I have no problem downing the entire bottle in a matter or seconds when extremely thirsty. Sometimes I'll drink from it without screwing on the lid while at the tap so that I can top it off before leaving.P.S. For gods sake, don't make the same mistake that I did. When you wash this thing out, remember to unscrew the straw and take the filter out. It took a while but I finally got used to the taste of soap. Either that or all the soap has finally been rinsed out through use. Oh well. ¯\_(ツ)_/¯

I LOVE these water bottles! I stumbled upon these while browsing on Amazon, and was very hesitant on buying these due to their price. I had been using the Brita water bottles and was trying to use them up before getting any new bottles in general. I got frustrated with my Brita bottles due to the fact that the mouth piece would be exposed and they leaked a lot. Finally after one of my Brita bottles fell and cracked I decided it was time to get a more presentable/travel friendly water bottle to take around the city with me. I ordered my first KOR Nava and I have never looked back. I have ordered these for my mom, my boyfriend and more for myself. I find I drink MORE water and taking it with me MORE often. If I don't take it with me I feel thirsty and sad because I have really grown attached to it. It has already paid off for itself more times then the Brita bottles, I can take it with us when we go hiking, to festivals, to events and it always gets used. Hands down my favourite water bottle that I can't live without. I wish they made these bottles in a 1L size. Less refilling.

Very good and practical bottle, simple to handle and keep Clean.
