90-100: Exceeds clinical standards 80-89: Meets all standards 70-79: Acceptable accuracy <70: Below clinical requirements |
| 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 • Insurance coverage • 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

- All devices are purchased at retail price — we never accept free review units
- No advertising or sponsorship from device manufacturers
- Reviewers must disclose any potential conflicts of interest
- Annual third-party audit of our independence policies
Conflict of Interest Management
All team members and medical reviewers must complete annual conflict of interest declarations. Any potential conflicts are disclosed in relevant reviews.
Reviewers with financial interests in a device manufacturer or competing products are excluded from the evaluation process for those devices.
Funding Sources
Our testing program is funded through a combination of:
- • Educational grants from healthcare foundations
- • Subscription revenue from healthcare institutions
- • Affiliate commissions (clearly disclosed)
- • Research partnerships with academic institutions
Note: Device manufacturers have no input into our testing methodology, evaluation process, or final recommendations.
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.
