| Safety & Reliability | 25% |
• Adverse event rate • Device failure rate • Error handling |
90-100: Exceptional safety profile 80-89: Minimal safety concerns 70-79: Acceptable risk level <70: Significant safety issues |
| Usability | 20% |
• Setup complexity • Learning curve • User satisfaction |
90-100: Intuitive, minimal training 80-89: Easy to use 70-79: Moderate complexity <70: Difficult to use |
| Build Quality | 15% |
• Durability testing • Component quality • Warranty coverage |
90-100: Premium construction 80-89: High quality 70-79: Acceptable quality <70: Quality concerns |
| Value | 10% |
• Cost-effectiveness • HSA / FSA eligibility • Long-term costs |
90-100: Exceptional value 80-89: Good value 70-79: Fair pricing <70: Poor value proposition |
Overall Score Interpretation
- 90-100: Exceptional — Highly recommended
- 80-89: Excellent — Recommended
- 70-79: Good — Recommended with reservations
- 60-69: Fair — Limited recommendation
- <60: Poor — Not recommended
Clinical Evidence Grades
- Grade A: Multiple RCTs or meta-analyses
- Grade B: Single RCT or high-quality studies
- Grade C: Observational studies or case series
- Grade D: Expert opinion or limited data
- Grade F: Insufficient evidence
6. Real-World Validation
We validate our findings by comparing test results with published research and real-world user feedback:
Validation Approach
Clinical Literature Review
Comprehensive review of published clinical studies, FDA submissions, peer-reviewed research, and post-market surveillance data for each device.
User Feedback Analysis
Analysis of verified user reviews, reported issues, and documented experiences from actual device users to identify patterns and common concerns.
Manufacturer Data Review
Evaluation of manufacturer specifications, clinical validation data, warranty claims, and technical documentation against our test findings.
Comparative Analysis
Side-by-side comparison with competing devices in the same category and established industry benchmarks.

7. Disclosures & Ethics
Transparency and independence are fundamental to maintaining trust in our evaluations:
Independence Policy
- All devices are purchased at retail price — we never accept free review units from manufacturers
- No advertising or sponsorship from device manufacturers
- Affiliate relationships are clearly disclosed on all relevant pages
- Testing results are never influenced by potential commission earnings
Transparency Commitment
We are committed to complete transparency in our testing process and business relationships. Any affiliations, sponsorships, or potential conflicts of interest are clearly disclosed.
Our reviews are based solely on objective testing data and real-world usage experience. Affiliate relationships with retailers do not influence our testing methodology, scoring, or recommendations.
Funding Sources
Our testing program is independently funded through:
- • Self-funding: We purchase all devices and testing equipment ourselves
- • Affiliate commissions from device retailers (clearly disclosed on reviews)
- • Website advertising revenue (no device manufacturer ads)
Note: We maintain complete independence. Device manufacturers have no input into our testing methodology, evaluation process, or final recommendations. All devices are purchased at retail price.
Limitations
Our evaluations have inherent limitations that should be considered:
- • Testing conditions may not reflect all real-world scenarios
- • Individual patient responses may vary
- • Long-term outcomes beyond our testing period are not assessed
- • Rare adverse events may not be detected in our sample sizes
Always consult with healthcare professionals for personalized medical device recommendations.
