How I pick

Every guide runs the same five steps. Nothing makes the line-up without going through all of them.

1. Cast a wide net. I start with everything with real sales volume in the category — not just what's advertised, but what owners actually buy and talk about.
2. Read the owners, not the ads. I dig through owner forums, subreddit threads and long-term reviews looking for patterns: what fails at month six, what the marketing quietly omits.
3. Score the spec sheet. Power draw, sensor type, materials, warranty terms — the boring numbers that separate a good product from a good listing.
4. Hands-on where noted. When I've used the product, the guide says so. When the verdict comes from research only, it says that too. No pretending.
5. Pick a line-up, including the skip. A guide isn't "everything good" — it's one best overall, one budget, one splurge, and at least one popular-but-overrated product called out as the skip.

What knocks a product out

• Fabricated or incentivized reviews I can detect.
• Warranty games — "lifetime" that expires in 90 days.
• Spec inflation: "4K" cameras that upscale 1080p, inflators rated at zero duty cycle.
• A product I wouldn't put in my own car.
