Anntrue Collapsible Water Bottle Food-Grade Silicone Portable Leak Proof Travel Water Bottle, 18oz(Navy Blue)

Purchased for travel to Switzerland and it was perfect. Very happy we chose these, very light and doesn’t take large space in backpack.

I bought this for a trip and it has some good features, like that it collapses, the whole lids comes off and there’s a way to easily carry it or attach it to something.Two drawbacks: as with most every bottle of this type, the silicone is so flexible that it frankly becomes hard to deal with. It can be filled with water and pushing it into the bottle holder on a backpack requires effort because the material is so mailable.Also, the screw cap to drink from unscrews too easily and several times leaked - once all over a car seat and once in the bag while boarding a plane. If the bottle is full and you apply any pressure - like, to push it into the bottle holder of a backpack - the pressure builds up inside and unscrews it so water comes out.It’s not the worst design but it’s not the best.

I really like having this bottle for traveling. Because it can be collapsed, you can easily store this in your bag. I think the biggest con with anything silicone based. You always get that silicone smell and taste for awhile. It is bpa free. What's nice it does come with instructions on how to remove smell. They said boiling it for 5 minutes works but I just scrubbed and air dry a few times over the course of the week. The bottle is very easy to collapse and expand. Be aware when you do expand it to open the cap as it will not open correctly if you do not as it will not be taking up. The device is nice for traveling as you are able to pack it into you carry on easily and just fill it up once you are past TSA. You can also use it as a cup by consolidating the bottle. It holds a good amount of water. I would say it may not be enough for like a long hike but if you go to the gym this will work just fine. Overall I think this bottle is great to have but you need to thoroughly clean it to get rid of the new smell.

Got this as a space saver water bottle for my son. Trying to use to hydrate during swim practice, but not take up as much space in his gym bag. I really like the high grade silicone that makes up the bottle. It seems well made and hopefully will keep up with the abuse I'm sure it will get. The lid has a nice screw-on drinking cap that does not leak and stays pretty secure. The overall plastic cap comes off and makes cleaning easy.The one drawback I see is that when you use cold water (or other liquid) in the bottle, the silicone "stiffens up" and resembles more of a water bottle. But if the liquid is warmer, even room temperature, then the silicone softens up and it is less like a water bottle. It still works, but take a little getting used to about grabbing it, squeezing it (which could be seen as a benefit when using as well).Overall, I like the shape-changing feature and the silicone is easy to clean. It is a well made product, we'll just have to see how he can change habits to use it best. Overall a 4 stars for quality, features and concept, minus 1 for oddity in everyday use.

It is what It says it is. It's sturdy easy to use and folds up so small it can fit in your pocket. Especially nice in the backpack. We had issues with the big heavy thermoses wearing the backpacks down. Not a problem with this one

I purchased 2 of these for a recent Disney trip and was pleasantly surprised with quality! My husband and I used these for 2 days in Disneyland and 1 Day in universal. We opted to take our own bottles to refill instead of buying $3plus bottles of water in the parks. The bottles are sturdy enough that they hold their shape when set on a table without fear of tipping even when they aren’t full. We had no issues with leaking or taste/smell. To clean them after the trip I used a bottle brush with the bottle full expanded and allowed them to air dry completely before putting them away.

This is a pretty neat water bottle. The bottle is made of a sturdy silicone that can collapse when it is not full. I can see this being handy especially when traveling. Also the lid is nice I like the way it closes and keeps the drinking surface clean. It is well made and I can imagine it will last a long time.

The product is working very well so far and has met my expectations. The medium size makes it convenient when full, the seals do no leak and it collapses enough to make a difference. Plus I like the blue color.
