How We Test

Every product we recommend goes through the same process. When we haven’t tested something hands-on, we say so clearly on the page.

How we choose what to test

We start with what readers search for and ask us about, then shortlist products based on materials, brand reputation, verified customer feedback and price. We buy products ourselves or receive samples from manufacturers. Receiving a sample never guarantees coverage or a positive review.

What we test

• Materials and safety: we check what the product is made of and favor non-porous, body-safe materials.
• Comfort and design: shape, size, flexibility and how easy the controls are to use.
• Noise: measured with a decibel meter at [30 cm] on the highest setting.
• Battery life: run time from full charge on a [medium] setting, plus charging time.
• Water resistance: we verify the stated rating with a [rinse / submersion] test.
• Cleaning: how easy the product is to clean and dry properly.
• Value: performance compared with similarly priced alternatives.

How we score

Each product receives a score out of 5 based on the criteria above. Safety issues are disqualifying: we won’t recommend a product we have concerns about, no matter how well it scores elsewhere.

Expert review

Articles that include health or safety information are reviewed by a qualified professional before publication. You’ll see the reviewer’s name and credentials at the top of each reviewed article.

Keeping reviews current

We re-check prices and availability regularly and update our recommendations when better products come out or guidance changes. Each article shows when it was last updated.
