How we pick
What we actually do, what we explicitly do not do, and the criteria every roundup on this site is ranked against. Including the part where we say we do not run a lab.

What we actually do
We research the category exhaustively. In practice that means four things:
- Manufacturer specifications. We pull the brand’s own product page for every product we name and take capacity, dimensions, materials, mechanism ratings and warranty from there. Where a brand publishes a figure, we cite it and attribute it as theirs.
- Current retailer listings. Every product on this site was confirmed to be currently sold at the time of writing. A discontinued product gets removed and the roundup re-ranked, not left in place with a dead link.
- The pattern of what long-term owners consistently report. Characterized honestly as aggregate sentiment — never as a quoted review, never with a star rating, never with a review count.
- Published findings from organizations that run real lab tests. Named and linked, and always framed as theirs. If a testing organization bought ten cans and ran a protocol, that is their work and we say whose it is.
What we do not do
We do not run a product-testing lab. We have not bought and side-by-side tested every can on this site, and we will not pretend otherwise.
Where we have used a product ourselves we say so explicitly on that page. Where we have not, our recommendation rests on published specifications, the pattern of owner-reported experience, and testing published by others — all of which we cite. You will not find the phrases “in our testing”, “we tested”, or “after 40 hours of testing” anywhere on this site, because they would not be true.
This is worth stating plainly because the alternative is common. Two of the sites competing with us for these search results assert a testing methodology without describing a single test. We would rather tell you the limits of what we know. It is also why our roundup titles say “compared” rather than “tested”.
We also do not invent credentials. There is one author here, and the only thing claimed about him is that he is the hands-on owner behind the publisher. No certifications, no years-in-industry figure, no count of products reviewed. More about who writes this.
How picks are ranked
The same criteria apply to every roundup, in roughly this order of weight. Where a criterion does not apply to a category — bag fit on a compost caddy, say — it is dropped rather than fudged.
- Bag fit and liner behavior. Whether the bag is retained properly, how badly it overhangs, and whether the can needs a proprietary liner. This is the most-complained-about aspect of the entire category and it is weighted first.
- Odor containment by design. Whether the lid seals, whether there is a filter slot, and whether the construction traps residue. Design, not deodorizer.
- Opening-mechanism durability. The pedal linkage, sensor or hinge, and the manufacturer’s published cycle rating where one exists. This is the part that fails.
- Cleanability. Removable buckets, smooth interiors, and whether liquid can reach the mechanism.
- Capacity honesty. Stated volume against usable volume, and whether the shape suits the space it is sold for.
- Material and finish. How it holds up cosmetically, which is how most cans actually fail.
- Warranty. Published length and what it covers.
- Cost per year over expected life, including consumables like proprietary liners, batteries and filters — not sticker price.
Why every product has a stated drawback
Every product on this site carries a named flaw, every time, in a section headed “What we’d flag”. That is a structural rule, not an editorial preference — the page template will not render a product without one.
Two reasons. First, no product is right for everyone, so a roundup where nothing has a downside is a sales page wearing a review’s clothes. Second, and more practically: a stated drawback is the only honest substitute for the testing claims we are not going to make. If we cannot tell you we ran a lab test, the least we can do is tell you what we would want to know before buying.
How we handle prices
We do not print prices. Retail prices on these products change weekly, and a stale number on a page is worse than no number — it is a figure a reader might plan around that stopped being true a month ago. So we link you to the current price at the retailer instead of guessing at it.
For the same reason you will not find a star rating or a review count anywhere on this site. Those numbers are not comparable across retailers, they are gameable, and quoting one would imply we had verified it.
Where we discuss value, we discuss it structurally: what the premium buys you mechanically, and what it costs per year including consumables. The longest worked example is here.
How and when pages are updated
Every page carries a visible “last reviewed” date, distinct from its publish date. It only moves when the page has genuinely been re-checked. We do not bump dates to look fresh — a false freshness date is the same category of dishonesty as a fabricated review.
| Page type | Reviewed | What we check |
|---|---|---|
| Roundups | Quarterly | Still sold? Discontinued? A new model that beats a pick? Links resolving? |
| Comparisons | Quarterly | Both products current, and any spec or warranty change |
| Model reviews | Quarterly | Still sold, or superseded by a new generation |
| Reference guides | Every 6 months | New sizes, and any reader-reported error |
| How-to and fix-it | Annually | Still accurate, and whether a better method exists |
| Trust pages | Annually | Plus immediately on any change to our process |
| Hubs | Quarterly | Tiles still point at the current top picks |
How to tell us we are wrong
Email contact@lidandliner.com or use the contact form. If you can point at a manufacturer page that contradicts something here, even better.
We commit to two things. We will correct errors. And where a reader could have acted on the error — a wrong dimension, a wrong compatibility claim — we will note the correction on the page rather than silently patching it.
