Tommee Tippee PrepGo Portable Formula Feed Maker with UV Steriliser, 425913

Tommee Tippee PrepGo is a portable formula feed maker with a built-in UV steriliser lid.

What to know before buying

The listing says to check the feed temperature before feeding and to use a prepared feed straight away. Its two-minute claim applies to a 120ml feed cooled to 40°C, not every feed size or condition. Claims about NHS guidance, leak-proofing, sterilisation effectiveness and quiet operation are listing statements, not independently verified results.

Who is it for?

A good fit for

Parents who prepare formula feeds away from home and want a flask with an integrated UV steriliser lid.
Buyers seeking a rechargeable, compact feeding option for outings or night feeds, and who find the stated 240ml flask capacity suitable.

Less suited to

Those who need a machine for automatically dispensing and mixing powdered formula. The described process calls for adding boiling water and formula to the flask and shaking it.
Those who need a larger-volume preparation than the listed 240ml flask can hold.

Aggregate ratings are strongly positive, with most ratings in the five-star category and the remainder in the four-star category. No written customer feedback is supplied, so these figures do not identify what users liked or any practical concerns.
