About RetroOilReview

RetroOilReview exists to help people find the best oil diffusers and save money doing it. We are an independent review and coupon site focused exclusively on the oil diffuser niche -- retro, waterless, ultrasonic, reed, and everything in between. Our goal is to provide honest, detailed information so you can make an informed purchase.

We believe that home fragrance should be accessible, natural, and thoughtfully designed. That is why we focus on brands like Charabanc Aroma that prioritise craftsmanship, pure ingredients, and unique design -- and why we work to surface the best available discounts.

Every product we review goes through a standardised testing process:

• Scent Diffusion Quality: We test how quickly and evenly the scent fills a standard room, and how concentrated or authentic the aroma is compared to the raw oil.
• Build and Materials: We assess the quality of construction, materials, weight, finish, and durability.
• Design and Aesthetics: We evaluate how the diffuser looks in a real living space -- bedroom, lounge, study, and bathroom environments.
• Noise: We measure perceived noise levels in a quiet room during operation.
• Ease of Use: We time the setup, evaluate the controls, and assess cleaning and maintenance requirements.
• Value for Money: We compare performance against price, factoring in available discounts.

Ratings are assigned on a 1--10 scale. We never inflate scores and we always list both pros and cons.

Our editorial team follows strict standards to ensure all content is accurate, helpful, and trustworthy:

• Research-Based Reviews: We review products based on thorough research, product specifications, user feedback, and publicly available information. Where possible, we supplement our analysis with direct product experience.
• Coupon Verification: We regularly check coupon code availability and update our listings accordingly. Coupon terms may change at the discretion of the brand; we aim to keep our information current.
• Transparency: We disclose all affiliate relationships. See our Affiliate Disclosure for full details.
• No Paid Placements: Brands cannot pay for higher ratings or featured positions. Our recommendations are based on testing results only.
• Regular Updates: All pages display a "Last updated" date. We refresh content and re-verify coupons on a regular schedule.

When we list a coupon code, we confirm it through the following process:

• We check the code is accepted by the store checkout system and that the advertised discount is applied correctly.
• We review the coupon terms (product eligibility, minimum order, expiry) and document them clearly.
• We revisit coupon pages on a regular schedule (typically weekly for featured codes, monthly for others) and update or remove listings as needed.

Despite our best efforts, coupon availability may change at any time at the discretion of the brand. We always recommend using a code promptly and contacting the store directly if issues arise.

We follow a regular content maintenance schedule:

• Coupon pages: Reviewed and updated weekly. Featured coupon codes are checked for availability on a weekly basis.
• Review pages: Refreshed when new product information, pricing changes, or significant user feedback warrants an update (typically monthly).
• Comparison pages: Updated when new products enter the market or existing products change specifications or pricing.
• About / Privacy / Disclosure: Reviewed annually or when policies change.

Every page displays a visible "Last updated" date that matches our sitemap, so both users and search engines can see when content was last reviewed.

We take trust seriously. If a product falls short, we say so. If a coupon has expired, we remove it. Our reviews include honest pros and cons, and our ratings reflect genuine evaluation -- not partnerships. We believe that long-term trust is more valuable than short-term commissions, and our editorial decisions reflect that principle.
