My bestie always used the old fashion way of boiling to sterilize and I have watched her struggle with boiling water on the stove and wait while her baby wailed.
I bought this one because I was tired of watching her waiting for the stove to start boiling the water and then wait for it to cool off a bit so that she could handle the items in the pot.
This sterilizer is so much more convenient. You can get a lot in there as long as your not doing too many bottles at one time.
She does not use a lot of bottles, I ended up getting this sterilizer to help her clean them faster. With a new baby any time saving options are better.
She loves this product, it is just the right size, it is easy to use. You can also use it to sterilize pacifiers, small toys, or anything else that is made out of plastic. She also uses it to sterilize her breast-pump parts. It is quick and easy to use, and no clutter.
