How We Review

Last updated: 8 October 2026

StackPiston reviews launches on JVZoo: the front end, every upgrade (OTO) and any bundle. Here is how we put each review together.

1. We collect the facts

For each launch we go through the vendor’s sales page, the JV page and the JV documents: what the product does, every price in the funnel, upgrades, bundles, coupons, refund terms, launch dates and vendor bonuses. Vendor pages often contain mistakes or leftovers from older launches, so we compare the sources and use the most reliable figure.

2. We use the product

Our team buys the product and uses it on a real project. The number of days tested is shown on each review.

3. We score it

Every review scores the product out of 10 on ease of use, features, output quality, value for money and support. Each upgrade gets its own verdict: Worth it, Optional or Skip. We tell you to skip upgrades we don’t think are worth the money, even though that lowers our commission.

4. We use AI tools to help

We use AI tools to help gather the facts from vendor materials and to draft parts of each review. Prices, links and launch times come from the vendor’s materials and our own records, and are checked automatically before publishing. Scores, verdicts and anything we report about using the product are reviewed by our team.

5. We keep it current

Launch prices often go up when a launch ends. We update prices and launch times after a launch. If you spot something out of date, email alerts@stackpiston.com.

How we make money

We earn a commission when you buy through our links, at no extra cost to you. Commissions never decide a score. Full details: Affiliate disclosure.
