The short version
- Factual errors get fixed with a dated note; drifting price ranges get updated silently — a range is a snapshot by definition.
- We don’t test products; we compile published testing, specs, safety standards, and owner-review patterns, and we say when we lean on someone else’s measurements.
- Prices, availability, and the safety standards we cite are US-only.
- Every fix that’s shipped is logged below, dated, and left up — nothing gets quietly scrubbed.
This site gets things wrong. Prices move, manufacturers revise specifications without announcing it, products get discontinued, and sometimes we simply make a mistake. This page says what we do about it.
What counts as a correction
Three different things, handled three different ways.
A factual error. A wrong specification, a misattributed source, a claim that doesn’t hold up. We fix the text and add a dated note at the bottom of the guide saying what changed. We don’t quietly edit and move on, because a reader who acted on the old version deserves to know it changed.
A price that has drifted. Every price on this site is a street range, not a fixed number, and every button pulls the live listing rather than a stored price. Ranges still go stale. We update them without a dated note, because a price range is a snapshot by definition and annotating every movement would bury the corrections that matter.
A recommendation we no longer stand behind. Sometimes a product gets worse: a revision cheapens the build, a company drops support, a subscription appears where none existed. When that happens we replace the pick and say why in the guide.
What we will not do
We will not remove a correction to make the site look cleaner. We will not change a recommendation because a manufacturer asked us to. We have no relationship with any brand on this site beyond the Amazon Associates programme, and no brand has ever been given a preview of a guide.
Known limitations, stated up front
These are not errors. They are the boundaries of what this site can tell you, and they are worth knowing before you rely on anything here.
We do not test products. We compile published lab testing, manufacturer specifications read skeptically, published safety standards, and failure patterns across large numbers of owner reviews. Where a conclusion rests on someone else’s measurements, we name them. How we choose sets out the full method.
Prices and availability are US-only, and so are the safety standards we reference.
We earn a commission when you buy through our links, at no cost to you. The commission rate does not vary between the products in a guide, so there is no financial reason to steer you toward one pick over another. See the affiliate disclosure.
Telling us about a mistake
Email beforeyoubuyguide@gmail.com with the guide, the claim, and where the better information comes from. A link to a manufacturer page or a published test is more useful than anything else you could send. We would rather hear it from you than leave it wrong.
Corrections log
18 August 2026, four guides. Four picks left the market and have been replaced: the Cooler Master Hybrid 1 gaming chair (Amazon listing dead) gave its slot to the Razer Enki X; the NZXT BLD Starter Plus (line retired by NZXT) to the NZXT Player One — a different tier, which the guide now says plainly; the Chipolo ONE Spot (line discontinued) to the Chipolo Pop; and the Cosori Dual Blaze (unavailable) to the Cosori TurboBlaze. Each guide carries its own dated note, and every replacement’s price was verified against its live listing today. Our Ninja vs. Dual Blaze comparison stays up for owners, with an availability note.
18 August 2026, coffee gear and coffee gifts guides. The retailer link for the Baratza Encore grinder pointed at an outdated listing. It now points at Baratza’s current listing for the same grinder. The pick itself is unchanged.
18 August 2026, site-wide. Different pages disagreed about how often prices are re-checked — some said weekly, others monthly. As of today the answer is weekly everywhere, and it is backed by a system rather than a habit: an automated sweep reads every tracked product’s live retail listing each week and flags anything outside its published range for human review. Every page now states the same cadence.
18 August 2026, About page. The page said we link to lab-testing publications when a conclusion depends on their work. In practice we name them in the text but do not link to competing review sites, and the page now says “we name them.” Separately, the linking policy was widened the same day: standards bodies and government agencies (NSF, FDA, CPSC, EPA, Energy Star and others) are now linked at first mention in guides.
3 August 2026, Baby monitors. The guide recommended the eufy SpaceView as a hybrid monitor, saying you could run it as a local radio monitor day to day and switch Wi-Fi on to view the feed on a phone. The SpaceView does not do that. eufy’s own specification sheets for both the SpaceView and the SpaceView Pro state that they are not Wi-Fi capable, and the product is sold on the basis that no app is required. The entire entry rested on a capability the product does not have, so the pick was replaced with the eufy Baby Monitor E21, which genuinely offers both a parent unit and app viewing. Found during an internal sweep, not reported by a reader.
3 August 2026, Baby feeding. The Spectra S1 Plus entry said the pump is “frequently covered in full by US insurance” and led with the line that it is often free through insurance. The suppliers who actually process these claims describe the S1 Plus as an upgrade item carrying an out-of-pocket difference that varies by plan; the pump usually covered outright under the ACA is the mains-powered S2 Plus. A reader acting on our wording would have been surprised at checkout. The entry now explains the distinction.
3 August 2026, Camping gear. The Coleman Sundome entry credited the tent with keeping rain out through a decades-refined floor and fly design. The fly covers only about half the tent body and the seams are not sealed; Switchback Travel, testing the six-person, found standing water inside after one moderately rainy night. The entry now says so plainly and the tent is framed as fair-weather. The Jetboil Flash entry also published a hundred-second boil time against Jetboil’s own published figure of 120 seconds per half litre. Both corrected.
3 August 2026, Strollers and car seats. The guide recommended the Baby Jogger City Mini GT2 and the UPPAbaby Cruz V2. Both are discontinued and replaced by the GT3 and Cruz V3. The GT3 entry also corrects a compatibility claim carried over from the GT2: the older model listed direct compatibility with a long list of car-seat brands, while the GT3 ships adapters for Baby Jogger and Graco seats and needs separately sold adapters for most Nuna seats.
1 August 2026, Price Index. The page reported 422 tracked price ranges across 92 guides. The corpus had grown to 494 ranges across 102 guides, and the counts of products under $25 and under $50 were understated at 39 and 107 against actual figures of 57 and 181. The per-department table was rebuilt from current data. Found during an internal audit, not reported by a reader.
1 August 2026, Gaming chairs. The Cooler Master Hybrid 1 entry published 31.2 pounds as the chair’s weight. That figure is the gross shipping weight in kilograms; the chair is roughly 58 pounds. The same entry credited four measurements to published testing at Tom’s Hardware when they came from Cooler Master’s own specification sheet, and described the chair as having a 24-inch seat when that measurement spans the outer edges including the side bolsters. The entry was rewritten and re-badged.
1 August 2026, Kids tech. The JLab JBuddies Studio 2 entry stated that the 95 dB volume-limit switch was one a child could reach. JLab places it inside the earcup for parent-only access. The entry also described wired use as useful on a plane, but wired mode on this model is USB-C only and airline seatback jacks are 3.5 mm. Both claims were corrected.
1 August 2026, Skincare. The CeraVe Resurfacing Retinol Serum entry said its encapsulated retinol releases slowly. CeraVe describes the retinol only as encapsulated and attributes slow release to the ceramides in its MVE delivery system. Corrected.
1 August 2026, Men’s grooming. The Merkur 34C entry priced 100 Astra blades at about $8 in two places. Current pricing is $10 to $13. Corrected.
