I'm so disappointed with this water bottle. There is a piece of silicone that has been blocking the straw so I'm unable to be to drink th straw effectively. Definitely not worth the money I payed for it

They bottle itself is okay. definitely not worth the price tag though. It just feel very poorly made with cheap materials. I have had the original KOR water bottle several years ago. and I quite liked it. But this new model is just bad. the white/black plastic feels so cheap and the mouth piece is weird to suck on. And the WORST, WORST part is the mechanical design of the bottle cap!!! the lock mechanism is just stupid. it only turns like 30 degree from open to locked position and there's not a 'click' or any indication of locked in place. no matter how you screw close the cap (properly fastened or tilted with a false close) they all feel the same in your hands when you turning the cap. so there's no easy way to tell/feel if you've close the bottle securely. and yup that happened to me. I thought I had screwed the cap on tightly but the screw grooves inside apparently wasn't alined so the entire bottle of water poured (not just leaked) all over everything in my backpack. literallly ruined everything in it. I mean yes it might seem like it's my own fault not capping the bottle tightly but this bottle is so not user friendly, aka inconvenient. who wants to work for a water bottle when it should be working for you. HATE IT.

The design and bottle itself is nice. However, when you close the lid and take the bottle anywhere (purse, backpack, car, etc.) it leaks everywhere. Unless you're using it as a tall glass.. the bottle itself cannot handle any travel whatsoever. Also, water likes to get trapped inside the cap, so when you do open it to take a sip there is water pouring out from the cap. Terrible design, unless mine has a flaw I don't know about. So disappointed, it almost ruined my electronics, wallet, and damaged my leather purse.

It has leaked since day one.  If you don't want the liquid to siphon out the top, you need to leave the lid a little loose.  I use powdered kool-aid in my bottle, when I tip the bottle back and forth gently to mix the powder, the container leaks. I've had the bottle about 3 months and now the pop-up straw function does not work any more. I have the larger 40 oz size and it does not fit in any car holder.  I was splurging on this water bottle and can not recommend it to anyone.

The lid of this bottle is too difficult to remove and it makes water taste odd if it's been sitting in there for any amount of time which leads me to believe it's no better than the plastic bottles I was trying to replace.  It feels cheap and poorly made.  Not worth it.

I should have returned this as soon as I got it but I already had one & loved it. The black gasket does not fit correctly & therefore it leaks anytime it is on a slant. In exercise class, it proves to be a disaster by leaving water on the floor, creating a hazard. Also when putting it in my car cup-holder, it leaks before I even get it in the holder. I'm very  disappointed & this wasn't a cheap bottle. I don't recommend this item.

Really not happy with this water bottle. The bottle leaks from the top screw on seal when drinking. The push down mouth piece does not seal when pressed in the closed position.

Im shocked by all the raved reviews for this bottle. Sure it doesnt leak, thats because the straw mechanism always gets stuck or blocked up and no matter how hard you try, water just won't come up. You have to literally dismantle the whole top cap and straw to get the water to flow again. Thats fine at home but my daughter is using this bottle mainly for school and A) teachers don't have time to constantly fix the straw B) I don't want so many pair of bare hands touching the straw and spout where my daughter's mouth is touching as well. Will never get this again.

I didn't use this until a month after I had purchased it. A week after use, the plastic loop near the cap broke, so I couldn't hold it from there anymore. A month later, the rubber piece on the cap broke off, so now the cap doesn't snap back on its own when opened. This bottle is slowly falling apart! I'm disappointed because I really loved it at first! Now I don't even know how much longer it'll last.

I've never given a negative review before, but the firm that supplied this water bottle apparently didn't do much (any) quality assurance. It simply doesn't open. I've searched for online reviews and instructions to make sure I'm not doing something wrong, and in each case the example is simply pushing the button for the lid to open. In the bottle I received, it doesn't work. Meanwhile, the meter doesn't turn either. Did no one at the manufacturing plant doublecheck that the bottle actually opened? Apparently not. I probably just received a lemon of a product, but still it's disappointing.

I love the design of this bottle and it's easy to transport and drink from. However, as others have noted, it randomly leaks. I'll drink water from it and then water just spouts out from the collar for no reason. I'd live with that, but there's a HORRIBLE plastic smell from the lid. I've tried washing it and it isn't dissipating. Disappointed.

I thought I would LOVE this water bottle because it came highly recommended.  But it keeps leaking!  It is driving me crazy.  My old water bottle I could put in my bag and not worry about it.  This leaks every time.  I'm going to call the company, perhaps I just got a bad one?  Very disappointed.  Will repost after I speak with them.

Really upset with this water bottle! After a short time of little use the bottle does not close and leaks! I hope that this issue can be rectified, but until then 1 star.

This water bottle is horrendous. It constantly leaks when drinking from it. I will take minutes upon screwing the cap on to try to ensure that it is screwed on as tightly and evenly as possible, and yet I end up covered in water. I am VERY disappointed with this purchase.

Terrible water bottle for the fact that
I have two paid $33 for each one
And the plastic cap/holder on both at the lid have broken off

I really liked this water bottle when I first got it. Now, after about 6 weeks it no longer works. When I try to sip from the straw I get nothing but air. I've tried everything with the straw but it will not work. Tried other straws and nothing works. Very disappointed.
