How the tags work
Every tool has an ownership or measurement tag. The writing identifies Jerry's firsthand notes, listed facts and research conclusions so you can see what supports each claim.
Jerry's firsthand notes
These describe Jerry's experience with the particular tool, using observations he has actually shared. An ownership record alone does not supply a story about using it. Where no firsthand notes are available, we say so.
Research conclusions
We synthesize the product documentation and reviews collected in our research archive into explanations of features, compatibility and tradeoffs. Published research sections link to the supporting sources and distinguish a source's claims from our interpretation. When sources disagree or leave a question unanswered, we keep that uncertainty visible.
A review written by someone else stays attributed to that source. A claim about performance stays attributed to the person who reported it. Measurements earn the tested tag only when the page supplies our measurement evidence.
Who pays for what
Nobody pays for a tag. If a maker ever supplies a unit, that page says so near the top, in plain words, for as long as the page is up. That is the rule in the FTC's Endorsement Guides (16 CFR Part 255), and it is ours. For brands has the rest.
What you will not find here
- Star ratings, scores, winners or "best" badges.
- Measurements nobody took, or test language on a tool nobody tested.
- Order numbers, prices we paid or purchase dates.
- Paid placements, or copy a brand saw before it went up.
Where the numbers come from
Listed specs on the tool pages and on Compare come from each product's listing as we recorded it. Store listings change, so a size or count may differ on the store's page today. Energy figures are our arithmetic from the listed amp-hours and the pack's nominal voltage, and Pack math shows the working. The maker's page is the authority.
Corrections
If a tag or a listed spec is wrong, tell us and we will fix the page.
