I love Lifestraw, I love clean water and I love that every purchase helps a child get clean water. I read about this bottle prior to purchase and I followed recommendations in hope I wouldn't have any issues with the mouthpiece leaking. No luck so far😲. I am frustrated to say the least. It's not a leak like from the cap it's in the mouthpiece, it spews out! I was going to the hospital to visit a friend and this thing wouldn't stop, finally I put the top back on it, I was embarrassed and wet. So, I will try and work this out and I will give another review. I knew this might happen, that's why I took extra effort, to no avail, as of now.

Almost perfect

I purchased this for a trip to India. It was so wonderful to be able to fill it up anywhere without a concern of getting sick, and to not contribute to disposable plastic water bottle waste. I do think there is room for improvement. I love that there is a handle top that screws onto the base top that holds the filter. The problem is two fold. 1. If you tighten the handle top you have to be careful to not also overly tighten the base top/mouth piece (as they screw in the same direction). There were MANY times that getting the mouth piece off to fill the bottle was a pretty significant struggle. 2. The handle lid attaches with a 1/2 turn. The reason I didn't like this is because it easily works itself loose. My intention was to attach the handle of the bottle through ... MoreI purchased this for a trip to India.

(I didn't want to wear a backpack during my daily explorations in sweltering heat). It was a great idea, but because the handle top doesn't attach with a full (or more) rotation turn, it kept working it's way loose. For some, these many not be an issue. However, I do think these are easily improved upon. I hope to see a new iteration in the future.

Good Concept

I purchased two of these for an extended backpack trip in Europe. The thought was these water bottles would allow us to access safe drinkable water everywhere. We could fill them from sinks or other local sources of water. The bottles are durable, stylish and seem to function properly however they have one engineering flaw that impaired our use and prompted me to return them. When you fill the bottle with water after it warms to ambient temperature every time you open the lid water spills out making a mess. This happened consistently with both bottles regardless of how full we filled them. I’m not sure if the metal insulated version would have the same problem but for us, with the plastic ones it was enough of an inconvenience that we didn’t want to continue using ... MoreI purchased two of these for an extended backpack trip in Europe.

High Maintenance

The instructions mention to burp the bottle before flying as it may overflow in flight. However this became a everyday thing for me. Leaving the bottle in a hot car, or entering a AC building it would overflow. Even in you "burp" or blow back into the straw water can over flow when there is large pressure change. My car's bottle holders often had water in the bottom, then it dipped on my while driving. If the bottle was in my back pack and I did not "burp" it I would find a wet pack later in the day. I do need a filter for micro plastics which is the reason I chose this bottle. Sorry LifeStraw, I love your products but this bottle was just not functional for me.side note: I have worked with your team on a solution a few weeks ago.

Lost our favorite bottle

We bought the Life Straws for a trip where we were advised to drink only bottled water. At first, since they are expensive, we reconsidered our purchase wondering if we’d ever use those bottles again with our normal hiking, biking, skiing activities. It took a bit to get used to the draw needed to get water since we are so accustomed to using water bottles without straws. We soon learned the value of the LifeStraw bottles and the reassurance we had drinking water from the airports and hotels. And, we reduced our impact on the environment by using our own bottle instead of multiple plastic bottles daily. We now recommend the LifeStraw bottle to friends even though we accidentally left ours sitting on a hotel check-in counter in Thailand.

Many more uses than anticipated!

When I first got this bottle I was thinking I would only use it when I was camping and backpacking. But actually I found it much more useful in my everyday life then initially expected. In fact, it has replaced my Nalgene (that's saying a lot).We live on a mountain well and our water has a distinct mineral well taste that is completely eliminated by use of this water bottle. I've started keeping it by my bed so that I don't have to go downstairs to our filtered water station in the middle of the night when I run out of water. I also now bring it on all my travels to eliminate microplastics and whatever other undesirables lurk in airport and city water. And it goes on hikes (see photo).So easy to fill. The straw does take some time to loosen up so that you can get ... MoreWhen I first got this bottle I was thinking I would only use it when I was camping and backpacking.

The straw does take some time to loosen up so that you can get water out of the water bottle easily, but stick with it and it's worth it.I love the design on the bottle. It fits in most cup holders (!), and the top is comfortable to carry by hand for shorter hikes. Anyway, in a seemingly more and more polluted world, this bottle is great. I'm going to buy one for each member of the family. 4 stars for the initial difficulty in sucking through the straw.

Ridiculous leaky bottle

I love the fact this filter bottle will remove micro plastics from drinking water. What I do not like is the leaking whenever there is a pressure change. If I have the bottle in my and the car gets warm, as in summer driving, the water will leak out of there mouthpiece. Then I have a puddle in my cup holder or it drips all over my lap if I try to drink when driving. Or, putting the bottle in my day pack's bottle holder, then driving an hour only to find water all over my seat when I remove the screw on cap. Or vice versa, take it out of the fridge and later find it leaking all over my office desk. Basically anytime there is a temp change (pressure change) the bottle leaks if the screw cap is off. Life Straw suggests to "burp" the bottle but this really in not a ... MoreI love the fact this filter bottle will remove micro plastics from drinking water.

Life Straw suggests to "burp" the bottle but this really in not a convenient thing to do especially while driving or when the bottle is in back seat of the car. I would return this bottle if I could find another filter bottle for micro plastics.

Similar to the draw of a milkshake

Definitely not the quality I expected. A bit like sucking a milkshake through a thin straw. If you are hydrating while the bottle is still mostly full and you set it down, water will continue to pull through the straw and it’ll puddle under your bottle and around the mouthpiece. This is a solid no-go from me. On top of that, you can’t hold much water in this in the first place. So of you’re planning on using it for hiking, be prepared to find water often. I bought two of these and all they are going to do is collect dust.

Under Pressure

The filter is a nice touch to ensure that you have clean(er) water wherever you go. It’s a bit weighty with or without water which may deter some buyers.My issue is when air pressure builds… whether in a plane or driving through the mountains… this bottle becomes a fountain. Twice on a plane and two other times in the Smoky Mountains, when I unscrewed the top water poured out everywhere and wouldn’t stop. I looked like I just p*ssed myself at 35,000 feet. Twice.The only thing I can think of is if you do actually p*ss yourself on a plane or in the mountains, just this water bottle and you’ll have an instant excuse! Silver linings.

replacement filters

Additional info on replacement filters should be included with each filter model ordered. it should include;- main replacement filter part number- charcoal filter replacement number.I read the online info on what the Go series filter does and does not remove from water. It appears as though the main filter harmful chemicals it does not remove is longer than what it does remove. And the charcoal filters' effective life is 25 gallons vs. the main filter effective life is 1000 gallons. That means a person would need 1000/25 = 40 charcoal filters to even be a comfort in an emergency. In general, filter replacement information is very vague and misleading.
