Sponsorship &
disclosure.

The headline.

RevApple's primary business is precision machining and finishing. That work is quoted and sold directly to customers, not through this website. Separately, RevApple Media, our reference library, may carry clearly labeled sponsorships and paid directory listings from industry suppliers such as machine and tooling makers, finishing and service shops, and material suppliers. A commercial relationship never changes which product we recommend, the order we rank them in, or how we describe them.

What you will see.

• Sponsored placement. Bought media. Outside editorial, in clearly labeled units. Never inside a ranking or guide.
• Directory listing. A paid, verified supplier profile in a directory, labeled as a listing.
• Editorial recommendation. Named by editors on the merits. Not for sale.
• Gift or loaner. If a maker provides a tool, material, or part for evaluation, it is disclosed at the top of the piece. We return it, donate it, or buy it at market price.

Direct, not networked.

Sponsorships and directory listings are arranged directly with the supplier under an individual written agreement. We do not run consumer affiliate-network links. Any material commercial relationship is disclosed on the page where it appears and is subject to the editorial firewall below.

FTC §255.

Our disclosure practices are designed to comply with the FTC Guides Concerning the Use of Endorsements and Testimonials in Advertising, 16 C.F.R. Part 255, including the 2023 revisions. Material connections are disclosed clearly on the page, near the recommendation, in plain language. This page is linked from the site footer.

What sponsorship does not buy.

• No paid placement in any ranking, directory ordering, or guide.
• No coverage in exchange for payment.
• No removal or rewriting of negative findings.
• No wording changes in exchange for consideration.
• No "right of review" by sponsors before publication.

Anyone who tries to negotiate the above is reported to our standards committee. Repeat attempts end the relationship.

Numbers move.

We timestamp specifications and pricing where we publish them. RevApple is not responsible for prices, stock, or specs on a supplier's own site at the moment of your visit. Confirm the spec, the price, and the terms with the supplier before purchasing.

Information, not engineering judgment.

Content is published for general informational purposes and does not constitute professional engineering, legal, financial, regulatory, or tax advice. Consult a qualified professional and verify the original source before relying on any information for a procurement, design, or compliance decision.

If something is off.

Report an undisclosed sponsorship, a sponsor placement inside editorial, or a stale price via the contact form (topic: Editorial) with the URL and the concern. Substantive corrections appear as a dated note on the page.

We update this Disclosure when practices change. Material changes are flagged in the site footer for at least 30 days. The "Effective" date reflects the latest revision.
