Diono Radian 3RXT Safe+ Convertible 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.

Sold and shipped by megababiesusa.com, megababiesusa.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. 60 checked facts, checked 2026-10-19T00:12:46.598Z. Research depth: trimmed read. Deep read: the store's own data and 12 outside pages (the store's own product page; manual; maker page; review; blog; regulator recall search (CPSC (United States)); regulator recall search (Health Canada); official safety test results (CREP, the Child Restraint Evaluation Program); official safety test results (NHTSA's Car Seat Ease of Use Ratings); official safety test results (ADAC's child seat test)), 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: CPSC's Diono recall search returned no records for Radian 3RXT Safe+. Health Canada's open data lists 13 Diono recall records, but none names the Radian 3RXT Safe+, so no recall was found applying to this exact model. Official safety test results were looked up directly with CREP, the Child Restraint Evaluation Program, NHTSA's Car Seat Ease of Use Ratings, ADAC's child seat test: CREP, the Child Restraint Evaluation Program (Australia and New Zealand): CREP's complete published list of 216 tested seats contains no Diono or Radian 3RXT Safe+ entry, so this seat has not been rated by CREP. NHTSA's Car Seat Ease of Use Ratings (United States): NHTSA's published list includes other Diono Radian variants, including the Radian 3QX, 3QXT and 3QXT+, plus other Diono boosters, but not the Radian 3RXT Safe+; only other variants or generations were rated. ADAC's child seat test (Germany, the UK and Europe): ADAC's list includes one Diono seat, the Radian 5 tested in 2016 with an overall grade of 5.5; the Radian 3RXT Safe+ itself is not listed. Not read, because they are member-only or refused RoboTrunk: Consumer Reports car seat ratings, Which? child car seat tests, JPMA certified products.

Questions we researched but could not confirm

Every fact above is cited. To find them we read the store listing, the manual, the maker's page, owner reviews, blogs, the recall records of CPSC (United States) and Health Canada and the safety test results of CREP, the Child Restraint Evaluation Program, NHTSA's Car Seat Ease of Use Ratings and ADAC's child seat test and searched for regulator recall notices, owner forums and video reviews. 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.

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.
