Munchkin Steam Guard Microwave Sterilizer

Under $20Checked Oct 29, 20262 sources

Our take

A cheap microwave steam sterilizer that saves counter space and fits tall bottles if tilted. A tester burned her wrist on the hot water, so open it carefully.

Microwave~4 bottlesUnder $20

Consider instead: Dr. Brown's Deluxe for an electric option.

Before you buy

Do you need it?Nice to have A time saver if you'll wash many bottles a day. A dishwasher basket or bottle brush does the job for many families.
Cost per monthAbout $1.67 a month over a typical 12 months of use. Our estimate; your use may be shorter or longer.
Secondhand?Secondhand with checks. Fine secondhand if it's thoroughly cleaned and descaled.
