Marketing Claims vs Reality
The marketing materials for this product contain several concerning misrepresentations:

- Manufacturing Origins
- The claim about German-made Tritan bottles by Bayer appears to be false. Tritan is actually manufactured by Eastman Chemical Company, not Bayer
- While DuPont has a presence in Japan, known as DuPont Japan Kabushiki Kaisha (DJKK), located in Tokyo, they do not manufacture proton exchange membranes.
- The actual membrane appears to be of Chinese origin, which contradicts their marketing claims about Japanese manufacturing
- Technical Specifications
The marketing materials show several technical inconsistencies:
- They incorrectly describe the proton exchange membrane (PEM) as a "filter" system
Design Flaws
Several practical design issues stand out:
- The narrow bottle neck creates a significant cleaning challenge, potentially leading to hygiene issues
- The membrane reinforcement element (referred to as "Star of stench") creates an area that's difficult or impossible to properly sanitize
- These cleaning difficulties could lead to bacterial growth and contamination over time
Safety Concerns
- The apparent misrepresentation of industrial-grade components as food-safe is concerning
- The difficulty in properly cleaning the bottle raises serious hygiene concerns
- The claims about "eliminating byproducts" seem optimistic given the design limitations
Value Proposition
At its core, this product appears to suffer from:
- Misleading marketing claims about materials and manufacturing
- Significant design flaws that impact usability and safety
- Questionable technical specifications
Recommendation
Given the numerous concerns about manufacturing transparency, design flaws, and potential safety issues, it's difficult to recommend this product. Consumers would be better served by:
- Seeking hydrogen water products with verified manufacturing claims
- Looking for designs that prioritize cleanability and safety
The combination of questionable marketing claims and practical design flaws suggests that consumers should approach this product with significant skepticism and consider alternative options for hydrogen water consumption.
