Review on 🚰 TRIWONDER BPA-Free TPU Soft Folding Water Flask - Collapsible Hydration Pack for Running, Hiking, Cycling, Climbing by David Bar

I received 2 of these as part of my order and 1 of them is leaking heavily from the cap. On closer inspection, the lids differ. One has a protruding feature (pictured left) and the other is flush with the top of the lid. The one that slides down doesn't flow well from under the cap no matter how tight it's twisted. Obviously this renders it unusable. Maybe the bad cap is for a different model of bottle? Either way, this is poor quality control. Other, minor issues are that the bite valve is very difficult to drink and requires a lot of force to compress and release liquid. I have a Solomon brand almost identical that doesn't have this problem. Also, I measured the volumetric capacity and the bottles only hold 16 oz to the neck compared to the 17 oz advertised. Overall I cannot recommend them. I'll look for something better.
