Review on 💦 50 Strong Brand Jet Stream Sports Squeeze Water Bottle with One-Way Valve - Team Pack – Set of 6 Leak-proof Squirt Water Bottles - 28 oz - Ideal for Bicycles - Made in the USA (Clear) by Eric Grayson

I didn't like that the advertised one-way valve was no different from a regular valve. The packaging clearly says "one-way valve" so I assumed that's what they meant, although it differs from the picture on the site. By squeezing the bottle with the cap open, it becomes clear that this is not a one-way valve. Again, the packaging label I included clearly states that this product is a "one-way valve". A picture of the valve is also attached for comparison with the photo on the product page.
