Philips Avent
3-in-1 Electric Steam Steriliser
8.1/10 overallAbout £50
An electric steam steriliser sized around the Avent bottle range, also usable as a microwave steriliser.
Philips Avent's 3-in-1 gives you the option of plugging it in as a standalone electric steriliser or, when travelling, using the same unit without its base in a microwave — genuinely useful flexibility that most competitors don't offer in one product. It's shaped specifically around Avent's own wide-neck bottle range, which slot in without needing to be angled or rearranged.
Against the Tommee Tippee Steri-Express, the trade-off runs the other way: the Avent is the better fit if you're using Avent bottles specifically, and the microwave option adds real travel flexibility the Tommee Tippee lacks. If your bottles are a different brand or an odd shape, they may not sit as neatly in the Avent's rack, and the Tommee Tippee's more general-purpose design would fit them better.
For Avent-committed households, particularly ones who travel with a bottle-fed baby, the added microwave mode makes this the more versatile of the two.
