YCT Collapsible Water Bottle 17oz（500ml），Travel Portable Sport Water Bottle，Reusable Silicone Foldable Water Bottles for Gym Camping Hiking (Black+Blue)

We took these to Italy with us. It is very light and easy to carry when empty. Once filled this becomes a bit of an unstable bottle. The clip won’t hold it full, it becomes too heavy. Also, it had bad taste.

I think they will serve their intended purpose, which is having a light weight, portable water bottle for refills while traveling in Europe. I like that they collapse down small and can be attached to our backpacks with the carabiner. *Amended review post trip: the carabiner was worthless, broke immediately. Just way to flimsy. I only used it one time on the trip, it became worthless when I could no longer attach it to my travel backpack, so I simply threw it away. Had I not been traveling in Europe, I may have had the patience to look for a better-quality carabiner and still used the bottle itself.

It was very useful for my trip. It is light to carry around. You have to keep the cap on at all times because when the bottle is full, it is wobbly and the liquid will spill. If you collapse the last tier, the base will be more stable and your liquid will not spill. There is a slight smell.

Did the job but no longer attaches to the carabiner because the circle is made of a flimsy silicone instead of being reinforced with plastic. Took it to a music festival and it broke due to the weight of the water.

Not sure what I was expecting when I ordered these? I bought them for a trip to Europe and we needed something to carry water but didn't have a lot of space. They are collapsable but don't get super small. The water bottle is flimsy even when full so doesn't fit in tight backpack holders easily and flops around when clipped on. It doesn't keep your drink cold at all and condensation forms on the outside of it within minutes. While I was grateful to have something to use, I should have just taken the metal bottle that is durable and keeps drinks cold for travel.
