This page explains how Power Tool Harbor researches, writes and updates its articles.
Our sources
We use manufacturer specifications, manuals and compatibility charts, published safety standards (for example ANSI Z87.1 for eye protection), and safety guidance from the Occupational Safety and Health Administration (OSHA) and the Consumer Product Safety Commission (CPSC). When a figure comes from a manufacturer, we say so.
What we do not do
- We do not claim to have tested products unless that is true, and we never invent test results, runtimes, ratings, awards or quotes.
- We do not recommend third-party batteries or modifications that a manufacturer does not approve.
- We do not publish Amazon prices, star ratings or customer reviews.
- We do not accept payment to include or rank a product.
Use of AI tools
AI tools help draft some articles. A person checks every article before publication; facts, numbers and safety statements are verified against sources, and anything we cannot verify is removed.
Corrections and updates
We review guides regularly. If you find an error, please contact us.
