How We Test Medical Alert Devices
Our testing methodology is built to evaluate real-world safety performance, not marketing claims. Every step below was finalized before the first device was purchased — we’re publishing it so you can evaluate our process independently, and hold our published rankings to exactly this standard, not a vaguer one we quietly relax when it’s inconvenient.
Purchase Process
All devices are purchased at standard retail price through normal consumer channels. We do not accept review units from manufacturers, we do not inform companies in advance that we’re evaluating their product, and we receive no pre-release access of any kind. Purchase date, price paid, and purchase channel are documented for every device we test.
The 30-Day Evaluation Protocol
Each device runs for 30 consecutive days before we record structured test data. That continuous wear period matters as much as the structured tests themselves — it’s where we observe battery consistency, charging reliability, connectivity drops, and button durability, none of which show up in a short unboxing-style review.
Protocol timeline
The 5 Evaluation Pillars
Our SNS Score is a weighted composite of five published pillars. The weights below were set before any device was evaluated and have not changed since.
| Pillar | What We Measure | Weight |
|---|---|---|
| Fall Detection Accuracy | % of simulated falls triggering an alert within 90 seconds, across 5 scenario types per device | 35% |
| Operator Response Time | Seconds from alert signal to a live human answering, averaged over 50 test calls at varied hours | 25% |
| False-Positive Rate | % of alerts triggered without an actual fall event — high rates cause seniors to disable detection entirely | 20% |
| Customer Service Quality | Response accuracy and wait time across 3 real contacts per company | 10% |
| Value & Pricing Transparency | Whether real 12-month cost is clearly presented or requires a phone call to discover | 10% |
SNS Scoring System
The SNS Score (0–5) is calculated directly from test data against this published rubric — it is not adjusted after the fact to fit a preferred outcome. Affiliate commission rates are reviewed only after a score is finalized, never before, and never as an input to the formula itself. See our Affiliate Disclosure for the full commercial-relationship picture.
- We do not publish test data we have not collected ourselves.
- We do not accept manufacturer samples or pre-release access.
- We do not allow manufacturers to review articles before publication.
- We do not claim credentials we don’t have — we are not doctors, occupational therapists, or certified safety inspectors, and we say so clearly.
- We do not suppress a “who should NOT buy this” section even when it reduces affiliate clicks.
Current Testing Status
SafeNest Senior launched in 2026. Our first structured 30-day evaluation cycle is currently underway. Current evaluation guidance on this site reflects manufacturer specifications, independent user reports (500+ verified reviews), and this published methodology — figures marked with a dagger (†) on our rankings are estimates, not measured results.
Measured data will replace those estimates when the first complete cycle is published. We do not publish partial data — results go live per device only after a full 30-day cycle is complete. See our update-cycle policy →
Why This Page Doesn’t Cite CDC, AOTA, or WHO
You’ll notice this page has no external clinical citations, unlike our Fall Prevention or Bathroom Safety guides. That’s intentional, not an oversight: this page describes our own internal process, not a health or epidemiological claim. Its credibility comes from being specific enough to check, not from citing an outside authority. When we do make a clinical claim — about fall statistics, grab bar heights, or lighting standards — you’ll find a direct source link on that specific page.
Frequently Asked Questions
Do manufacturers pay for a better score?
No. SNS Score is calculated from test data against the published rubric above. Affiliate commission rates are reviewed only after a score is finalized, and they are not part of the scoring formula in any way.
How do I know the “estimated” figures on your rankings are trustworthy?
They’re clearly marked with a dagger (†) and explained on every page that uses them — they come from manufacturer specifications and independent user reports, not from our own measurement, and we say so directly rather than implying we’ve tested something we haven’t.
When will measured (not estimated) results be published?
Per device, after each device completes its full 30-day evaluation cycle. We don’t publish partial results, so there’s no partial-data version of a ranking floating around before the complete cycle finishes.
