Nefeeko Collapsible Water Bottle, Reuseable BPA Free Silicone Foldable Water Bottles for Travel Gym Camping Hiking, Portable Leak Proof Sports Water Bottle with Carabiner

Bought this for an international trip and it was great! We didn't care so much about keeping the water cold, more so just having water with us while we walked all over Europe. It was nice and lightweight, and we hooked it onto my purse when we were walking around. It was nice to collapse it during travel. So much easier than a big metal one.

This is one of those times when I'm so glad I ignored some of the reviews! After washing this it with hot soapy water, letting it air dry, there was no rubbery aftertaste. Also whoever said it was unstable when fully extended and fill must have a defective one. It's very stable! I love this and am so glad I bought it!

Works as expected. Great for traveling - light weight, stands on its own, but collapses easily when empty. And it does NOT have the smell others are complaining about. However, it is hard to get it in the side pocket of a backpack if it is even a little tight or the backpack is full. The material is “grabby”, so if the backpack material isn’t slick nylon, it is impossible to get it in the side pocket. Nevertheless, we found it useful when traveling, and it did not leak when put in the upright position inside the backpack. Not ideal but it did keep us from having to buy water everywhere while we were on our trip.

The media could not be loaded. Reviews of the smell and taste after initially opening the bottle are correct. It feels like it is coated in a powder and even after multiple washes the smell and weird taste still lingers. More washes and drying the bottle helps. Using the bottle helps as well. I also used the filtered water I was going to drink to vigorously rinse/wash the inside of the bottle. Full expanded and trying to rinse all compartments. When I did that, I saw a lot of milkyish residue come out. And the weird taste and smell dramatically reduced. Hoping with prolong usage, that will no longer be an issue. There is no structure to the bottle (as it needs to collapse) so be careful when filling the bottle with water. Takes time to get used to drinking from it with the lack of bottle structure. Easy to collapse/bend with water in it as well. When this occurs, water does spill out. Do not try to change the shape of the bottle with the cap on. Will mis-shapen bottle. Collapsing and expanding bottle should be done with bottle cap open. I really appreciate that it’s light weight and ability to collapse and take up less space when needed. Fits in the bottle holder in my bag and comes with the clip that can be placed on my keychain or pant loop. I’m excited to use it for hiking and traveling.10/2/22 Update: The company reached out and this is what they said. Hope that helps.About Taste or Smell - Our water bottle is made of BPA FREE material, and passed certification of Food and Drug Administration in America. Please do not worry about its safety. If possible, please wash the bottle thoroughly with purified water. The water in the ordinary water pipe generally contains bleach substances or similar disinfection components, due to the particularity of the silica gel material, its molecular structure will adsorb some other substances in the water, which may appear as you see the white powder. The silicone material has very good stability, these white powders are not the material of the water bottle itself, you can rinse it directly, so please don't worry. Here are some advice to get rid of the silicone smell. Please add some dishwashing liquid or lemon slice in BOILED WATER, immerse the whole bottle and its cap in the water for 2 hours, then wash the bottle with clean water completely.

From day one, I followed the directions to clean this bottle. Then following that I added high quality local water to it. About an hour later I got my first taste and it was awfully tainted with a foul flavor. Not sure the claim that this is food safe silicone because even after using a safe dilution of hydrogen peroxide to try to "correct" the corrupted bottle, it still had the same foul taste when it was containing only water. I suggest people drinking flavored drinks are not aware that the bottle imparts some chemicals to whatever you add to this bottle. Flavored drinks will perhaps mask the foul contamination but it sure can't be good for any kids. Food safe silicone is misleading. I found mold growing on the walls of the bottle, within the first week, which was visible with the lime green bottle I bought which lets light through the walls. Anyone letting their kids drink from these bottles is putting there kids at risk. Those rating it great for kids might not be aware of this issue because they bought bottles that don't let you see though and therefore the mold isn't obvious. Buyer beware especially if you are using these for your children. I returned mine. Thank goodness my adult son suggested I only buy one to try it. Initially I was going to purchase several for the family. I don't know what quality controls were in place during manufacturing and storage, prior to delivery, but I'd suggest from my personal experience that something is really wrong with these... in terms of health. Otherwise the concept is great. They are soft and flexible and compress to smaller shape when you have less than a full liquid. I wanted this to work but it severely missed my expectations. I also was unable to remove the mold using a quality bottle brush. Tried everything to make this one work but I gave up once I realized there was mold and a foul taste that never goes away.
