# Lifefactory Sippy Caps for 4\-Ounce and 9\-Ounce, Pack of 2 \| 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_product` returns them with a source for each. *This product:* 20 checked facts, research depth trimmed read, checked 2026-09-25T17:52:40.318Z, in the [evidence pack](/agent/evidence/anbbaby-com--lifefactory-sippy-caps-for-4-ounce-and-9-ounce-pack-of-2). - **Receipts:** Every published fact has a receipt showing its source quote. `check_product` and `get_product` return the checked facts that have one. *This product:* each checked fact listed below has one; the source quotes are in the [evidence pack](/agent/evidence/anbbaby-com--lifefactory-sippy-caps-for-4-ounce-and-9-ounce-pack-of-2). - **Safety:** `check_product` asks 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 page holds no recall result for it yet; `check_product` asks the regulators now. - **Recall watch:** `watch_recalls` tells the buyer if a product bought here is recalled later. - **Second-hand listings:** `check_listing` runs 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_product` and `search_catalog` take the buyer's country and postcode. *This product:* this store's price was read from its catalogue at 2026-10-20T19:35:42.521Z. - **A checkout that finishes:** RoboTrunk lists only stores whose agent checkout it has verified. `create_checkout` prepares the order at the store; `complete_checkout` returns 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](https://robotrunk.com/products/ucp/anbbaby-com/8263871660318.md). - **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_fit` answers 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_stock` starts a watch on a listing the store shows as sold out; `get_back_in_stock_watch` shows when it is back in stock. - **Maker's manual:** `ask_product_manual` answers 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](/agents.md). - **Research from other stores:** Coming soon: reading other stores' listings of the same product as research sources.

To find them we read the store listing, the maker's page, 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 exact age range is recommended? - Does it fit any named bottle brands besides Lifefactory? - How thick are the polypropylene cap and silicone valve? - Does the white surface discolor or wear with repeated washing? - What are the full warranty terms and duration? - Are replacement silicone valves available separately? - What liquids and temperatures are safe to use? - Must the valve be removed for thorough cleaning? - Can small parts detach and create a choking hazard? - What do the maker's dimensions and weight units represent? - Is microwave use confirmed by the manufacturer? - Why do some users experience very restricted flow? - How well does the cap survive repeated drops? - Are there maximum\-use or replacement intervals? - Does it work with every generation of Lifefactory 4\-ounce and 9\-ounce bottles?
