I didn't expect it, but it's really very convenient. You don't need a bulky sterilizer to clutter the kitchen counter and it does the same job with much less money. Just a little water and 6 minutes in the microwave. The only downside is that it doesn't fit large bottles upright.

Very good and easy to use. It requires 200ml of water and the cooking time depends on the wattage of the microwave. In my case, with a microwave of 1,000 watts, I set it for 8 minutes.
