How we research

• We start with the problem you are trying to solve, not a product list.
• Comparisons are built from manufacturer specifications, manuals, and public safety or government sources. Each page links its sources.
• We do not claim hands-on lab testing. If we ever test a product ourselves, the page will say so plainly.
• We do not publish star ratings or prices, because they change constantly. Always check the retailer for current details.
• We include a “who should skip this” section on buying guides, because the right answer is sometimes “don’t buy anything.”

How we make money

Some links are affiliate links, including Amazon. If you buy through them we may earn a commission at no extra cost to you. That never changes what we recommend. See the full disclosure.
