I wanted to love this water bottle so badly, but I cant. My first issue is that about half of the time when I open the bottle, water pours out of the top. I am a healthcare worker, and I have had water or juice pour all over my scrubs more times than I can count due to this water bottle!! I contacted customer service, and they explained that this is a pressure issue, and that the "fix" is the untwist and open the bottle prior to opening the top. I run outside and commute to work by foot -- I wanted to keep the bottle on me for hot day and quickly pop open the top for a drink. However, customer service is saying that prior to each sip, I need to untwist the top, let the pressure out, retwist it on, and then open the straw/top. This is incredible inconvenient for what should be a simple water bottle.

Additionally, I dropped the water bottle from my chair (about 2 feet off the ground), and there is now a tiny crack in the bottom. I didnt notice this at first, because the drop was so minor/short, and I thought nothing of it. However, after leaving it on my table for 30 minutes, I came back to find water all over my desk, and discovered the sliver of a crack on the bottom.

I wish I could return this water bottle/get a refund or a replacement.

First of all, I love the larger size of these kids' bottles. All our other water bottles are 12oz., then we go to the beach or on the boat and the kids guzzle it down in an instant. This will greatly reduce the number of times I have to fill up their water bottles. Also, as long as it is closed, it does not appear to leak for us. My 4-year-old brought her "new" bottle into my bed last night, I didn't even realize it until the morning, but because she knew to put the straw down it didn't leak, PHEWWWW. I have a kids' bottle from another brand that was completely tightly closed and it still poured out almost entirely in my bag. So, for me, I am a fan of the Owala over that brand. And like the other reviewer said, when liquids go from cold to warm they expand, that's why milk cups always leak when you add new cold milk to them, too. It just is what it is with water bottles. I haven't even experienced that yet, though.

First off I must say that I received a 24 ounce flip bottle to review through the Amazon Vine program (I didn t pay for it but do get a income tax bill for every item I review). That said, I love it so much I will be buying the larger version. I have several different stainless steel bottles and so far I like them all but none felt like thee one. Until this one. It is the second brand I have had that was triple instead of double insulated. This one keeps water so much colder for longer.

The last bottle I bought was the other brand I own that is triple insulted. I compared their temps. Both started at 35 F straight out of the fridge. I did not add ice. Within 3 1/2 hours the other brand was at 66.3. Probably because you can feel the cold on the outside of that bottle,. Whereas with this bottle, you are chilling your hands. It took this bottle over 24 hours to get to 66.2.

I have MS and live in a warm climate, if water cannot stay cold, the bottle is useless to me, overheating means I get sick. This is my bottle of choice now. It actually keeps my water as cool as it claims, even without ice.

I had only recently heard about you guys and I'm so glad I did!! I have never ever had a water bottle that kept water so cold for so long. I will be ordering more because now my entire family wants one, and that says a lot!! I have always had problems getting my husband and son to drink water and now my husband drinks more water than ever. Thanks to the birthday bash I got a buy 1 get 1. I couldn't have been more excited .thanks owala for keeping my family hydrated and also producing hands down the best water bottle ever. I do have something I would like to add this does not pertain to the flip top though. I'm not quite sure about the free sip bottle because it doesn't make much sense to me if there is a huge hole why do you need a straw? I was looking on your website and I saw them and I just don't understand it. If you can enlighten me that would be great.
