Rank #8 in Best Bottle Sterilisers 2026: 10 Ranked, and the Numbers That Don't Add Up
MAM Microwave Steriliser, Grey
Price and rating as shown on Amazon when we collected them. Both change.
The MAM Microwave Steriliser is the eighth entry in this guide: a grey two-level tub that goes into a microwave instead of sitting on the counter with a plug. MAM's bullets put the whole cycle at 5 minutes, with contents staying sterile for up to 24 hours if the lid stays closed, and the price is £30.40 against a 4.6 rating from 209 ratings.
Two numbers on this listing are worth reading against each other. The bullets say the steriliser takes up to 6 bottles with accessories across two levels, while a reviewer on the same page reports fitting 7 full size bottles. The bullets also quote a height of 16.5 cm, where the spec table on the same page says 28 x 28 x 16 cm. And the star breakdown adds up to 100 ratings, not the 209 the listing claims at the top.
Everything on this page comes from the Amazon listing as it stands, not from any testing we have carried out.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“This is way better than the browns one we were using, wish we bought this earlier. We fit 7 full size bottles in here. We put the white rubber ring and teat inside the bottle, and the top and base together. It sterilises perfectly. Well worth the money and it is strong sturdy plastic with two trays.”
Verified purchase“Super easy to use, great size and doesn't take up too much room in kitchen. The lid doesn't fit in our microwave but we've just used without and all had been good. Been using for 7 months and really pleased with the quality of the item.”
