DIONO Radian 3QX Latch All in One Convertibles Car Seat | live price, prepared checkout
Built for shopping agents: what RoboTrunk does for every product
We asked shopping agents, including Meta's Muse first-hand, what they need from a store. This is what they asked for, and what we have built.
RoboTrunk is working through its catalogue, so a step may not be done for this one yet. Where a step is done per product, the line ends with what is done for this product.
- Deep research: We read the maker's manual, independent reviews, video review transcripts and the store's own page, and publish each finding with its source and the date read.
check_productreturns them with a source for each. This product: 28 checked facts, research depth trimmed read, checked 2026-09-25T04:14:53.215Z, in the evidence pack. - Receipts: Every published fact has a receipt showing its source quote.
check_productandget_productreturn the checked facts that have one. This product: each checked fact listed below has one; the source quotes are in the evidence pack. - Safety:
check_productasks the product-safety regulators live (US CPSC, NHTSA and FDA, Health Canada, the UK's OPSS, Australia's ACCC) whether a recall names a product, listed here or not, and flags a match with its notice; a recall never blocks the buyer. This product: this listing matches a model named in a regulator's notice (Health Canada and Transport Canada, 2024-11-25), as the index stood on 2026-09-25; the notice is listed below. - Recall watch:
watch_recallstells the buyer if a product bought here is recalled later. - Second-hand listings:
check_listingruns the same recall check on a second-hand listing someone found, and adds what the listing leaves out and the price new. - The real price: The full price to the buyer's country, with shipping and tax, each part quoted from the store's policy or, where a part is not settled, what the total depends on:
check_productandsearch_catalogtake the buyer's country and postcode. This product: this store's price was read from its catalogue at 2026-10-19T19:34:28.255Z. - A checkout that finishes: RoboTrunk lists only stores whose agent checkout it has verified.
create_checkoutprepares the order at the store;complete_checkoutreturns a link to the store's own checkout. The checkout can be finished in either of two ways: the person taps the link in their own browser, or their agent opens it and completes the checkout. RoboTrunk checks the store's total against a budget ceiling before it issues the link. Payment always happens on the store's own page, and RoboTrunk never holds the money. No store pays for placement; RoboTrunk may earn a commission from some stores via their affiliate programs. - Markdown copy: Every page has a Markdown copy: this page's copy.
- Photos and ratings: Search results carry the product photo and, where the store's own page publishes one, its rating (
search_catalog). - Fit answers:
check_fitanswers whether a listing fits a car, pram or bottle, with the exact quote from the store's page, or says it is not known. - Back-in-stock watches:
watch_back_in_stockstarts a watch on a listing the store shows as sold out;get_back_in_stock_watchshows when it is back in stock. - Maker's manual:
ask_product_manualanswers from the maker's manual with the exact passage and page, or says the manual does not cover it. - Tools and guide: Every tool and its description is at https://robotrunk.com/mcp; the guide is at /agents.md.
- Research from other stores: Coming soon: reading other stores' listings of the same product as research sources.
Sold and shipped by anbbaby.com, anbbaby.com; payment happens on the store's own checkout.

Checked facts
Each fact below was checked against the source it cites before it was published. Each carries that source's link and the time RoboTrunk read it. 28 checked facts, checked 2026-09-25T04:14:53.215Z. Research depth: trimmed read. Deep read: the store's own data and 8 outside pages (the store's own product page; manual; recall notice; review; regulator recall search (CPSC (United States)); regulator recall search (Health Canada); regulator recall search (ACCC Product Safety Australia)), each read in full by RoboTrunk and trimmed to its main content, then written up and checked. Facts from the maker or a manual quote the page word for word; what real users report is summarised with a link to the page read. Recall status was checked directly with CPSC (United States), Health Canada, ACCC Product Safety Australia: Transport Canada recall 2024718 explicitly lists Radian 3QX model years 2019–2024. Certain seats may fail Canadian requirements when installed rear-facing with UAS; use the vehicle belt rear-facing and contact Diono for the free remedy kit. The supplied CPSC search returned no US recall records. The Australian feed covered only the 100 most recent recalls and therefore cannot exclude older recalls. The Canadian index also lists later Diono recalls from 2025 and 2026, but their supplied summaries do not identify models, so applicability to this exact seat cannot be determined.

- Three-across and portability: Testing praised the narrow 17-inch body for three-across arrangements, but judged the seat heavy and bulky despite its ability to fold for travel..

- Rear-facing space: Although narrow side-to-side, the owner found it occupies substantial front-to-back room rear-facing—about 30–36 inches depending on vehicle-seat angle—making compact cars tight..

- Booster performance: Consumer Reports rated booster fit 1/5 and warned that the shoulder-belt guide can introduce slack as a child moves; the lap belt can also be misrouted easily..

- Crash-test durability: In Consumer Reports' comparative tests, all three rear-facing runs with a three-year-old dummy produced significant shell cracking. Forward-facing tests produced harness-slot and tether-area deformation, and one of two runs had harness webbing pull through the shell, although the dummies remained retained..

- Weight discrepancy: An owner reports that the Radian 3QX weighs 31.3 lb and is difficult to transfer between vehicles; Consumer Reports lists 31 lb, while the store lists 25.8 lb, so the sources disagree..

The full evidence pack, with every citation, source and gap.
Questions we researched but could not confirm
Every fact above is cited. To find them we read the store listing, the manual, a regulator's recall notice, owner reviews and the recall records of CPSC (United States), Health Canada and ACCC Product Safety Australia. We also chased the questions below across those sources and found no reliable answer, so you know exactly where the evidence ends and never have to guess.
- What are the exact assembled dimensions stated by Diono?
- Which tools are required for installation or mode changes?
- What are the complete seat-cover washing and drying instructions?
- Does the fabric resist pilling, fading and stains over long-term use?
- Does any paint or coating rub off with normal use?
- What are Diono's full warranty terms and exclusions?
- Is this specific seat's model year covered by the Canadian recall?
- Do the later 2025 or 2026 Canadian Diono recalls cover this exact model?
- What remedy applies to units outside Canada?
- How much clearance is required from the vehicle's front seat?
- Which specific vehicles have confirmed three-across compatibility?
Recall notice
This listing matches a model named in a regulator's notice, as the index stood on 2026-09-25.
- Health Canada and Transport Canada, 2024-11-25: Transport Canada Recall - 2024718 - DIONO (recall). The notice may cover only some serial numbers or dates of manufacture, which this listing does not show.
This listing is the brand and model a regulator's notice names. Two AI models judged it so independently. It does not mean the unit on sale is from an affected batch, that the store knew, or that the product is illegal where the store sells it; a US recall does not bind an Australian store. The notice may cover only some serial numbers or dates of manufacture, which a listing does not show. RoboTrunk never limits or blocks a purchase over a notice; read the notice and decide.
To buy this through RoboTrunk, pass merchant anbbaby-com, product_id gid://shopify/Product/4748741541974 and one variant_id from the list above.

This page is published by RoboTrunk, a store built for shopping agents. The store named on this page sells the product and ships it. RoboTrunk is not the seller and never holds the money. Buying works in one path. RoboTrunk's tools prepare a checkout at that store, then hand back a short-lived link. The person approves the total; once RoboTrunk has checked the store's total against it, the person is given the checkout link to tap in their own browser, or, if the person prefers and gives permission, their agent may open the link and finish there, and payment always happens on the store's own checkout page. RoboTrunk never takes the payment or sees a card. Where the rest of this site is: - /agent/story.md is what RoboTrunk is and how it works, in full. - /agent/tools.json is every tool, its arguments and its answers. - /agent/merchants is every store you can buy from through RoboTrunk. - /products/ucp is every store's indexed products. - /products/search is one search across every store, in plain words.
