Out of 3 i bought, only one worked. They get shipped with the straw already inserted, and in a bag. Due to that, any bumps cause the straw to lever against the cap and crack it. Once that, the bottle doesn't work because it's not sealed anymore. The bottles themselves are fine, but I can't cap them properly, or use the straw. The one that wasn't damaged works perfectly. I happen to be using it with rubbing alcohol to clean off a 3d printer plate.
