I was hesitant to purchase after people complaining about the taste of the water. I followed the instructions and the problem was solved! Easily clips on to backpack or purse

Good Bottles
I bought these bottles to leave in the car as spare water and they are pretty solid bottles.
So they definitely smelled/tasted of silicon when I first got them, but I followed the (poorly translated) instructions and boiled the bottles for a little bit. After boiling, the instructions recommend steeping red or green tea so I went with red and just left it in the recently-boiled water to keep it warm and steeping. I left the red tea in there for a good long while and eventually poured them out and rinsed. They smelled a bit like red tea for a short while but it wore away really fast and now the bottles don’t really have that silicon taste/smell at all anymore. UNLESS the bottle sits for a long time, but even then the taste is very subtle and not enough to be intolerable.
I will note that they seem decent-to-good-quality but the cap has a minor error: the “On” and “Off” label arrows. They face the wrong way! “On” points counterclockwise and the “Off” points clockwise so they’re completely wrong unless by “Off” they meant that you tightened the cap and are heading off. But this is just a goofy little translation error, aside from that the quality is generally pretty solid.
As is typical for these silicon bottles, it will flop down a bit when you’re trying to drink it and also crush if you suck all the water/air out. Really not a big deal though and is easy to get used to.

These bottles have a funny smell that never goes away.
I bought a few of these about six months ago. These bottles are made out of a strange plastic or silicon and the smell inside of them never goes away. When you buy these bottles, the instructions tell you to expect an unusual smell when you open them because of the kind of silicon they are made of. The instructions tell you how to supposedly get rid of the smell (which involves submerging them in boiling water for a little while), and then the smell is supposed to go away. I followed all the instructions and actually boiled them twice. But the smell never went away. The smell also seemed to make the water inside of them taste funny. I was concerned that there was some kind of chemical leaching into the water. Felt sort of unsafe, if I’m being honest.
The overall construction of the items was good, and it was easy to transport and collapse, but that was not worth the smell and taste problems that the silicon created.

Perfect for concerts
I have used this plenty of times for concerts and it is worth the money! It’s super lightweight when closed and easily stores!

El olor a plástico y el sabor de quitan después de lavar con agua caliente y un buen jabón 3-5 veces.
Lo
Mejor es que vas reduciendo su tamaño conforme tomas agua y así evitas espacios inútiles, me encantó que la puedes colgar de tu mochila o inclusive de tus pantalones.

Quality product, but a touch heavy for ultralight hikers
