How We Review

A look at how we decide what to feature and how we score it.

Our process

1. Research the field. We look at what's actually being used in the niche, the claims being made, and the refund policies behind them.
2. Read the fine print. Price, format, delivery, and — most importantly — the money-back guarantee.
3. Judge it honestly. We weigh genuine usefulness against the hype on the sales page, and we write down the real downsides.
4. Score and explain. Our rating reflects value-for-risk, not a promise of results.

What our ratings mean

• 4.2+ — Worth a low-risk try if the topic interests you.
• 3.5–4.1 — A reasonable option, but compare alternatives first.
• Below 3.5 — We'd usually steer you elsewhere.
