Clear verdicts. Visible evidence.
Each Keep Test will explain the product’s intended use, strengths, limitations and alternatives. A recommendation must make sense for a specific buyer.
Worth your money.
Strong enough in usefulness, performance and value to recommend.
Keep your money.
The trade-offs outweigh the value, or there’s a better way to spend the money.
Verdicts apply to a specific product, use case, price and review date.
Research-based Keep Pick
Based on documented specifications, relevant sources and comparisons. This label does not mean we handled or personally tested the product.
Personally tested
Used only when firsthand testing has occurred. The review will describe who tested it, how, for how long and any meaningful limits.
How comparisons work
One main KEEP. One genuine BUDGET KEEP when a strong lower-cost option exists. And PASS when the evidence gives us a reason to tell you to keep your money.
- 🏆 KEEP — Our Pick: The product we would recommend to most people based on the evidence.
- 💰 BUDGET KEEP — Save Your Money: A genuinely cheaper product—preferably around half the price or less—that still performs the core job well.
- ✕ PASS — Keep Your Money: Used only when the evidence provides a legitimate reason to spend the money elsewhere.
A comparison does not have to contain a PASS. Runners-up and second-best products do not automatically earn a PASS; the evidence determines the verdict.
What every review should show
- A verdict and review/update date
- Who it is for—and who should skip it
- Evidence and source links
- Benefits, limitations and alternatives
- Price context with a checked date when prices are quoted
- Affiliate, sponsorship or supplied-product disclosures when applicable
