I don't understand why people like this product!?! I bought this because I didn't want to boil my bottles anymore. I use both Avent and Dr.Brown bottles and everything seemed to fit just fine.... so what - After 4 minutes I had to rewash everything and then boil it because EVERYTHING I put in the sterilizer came out FULL of condensation and with a VERY VERY strong smell of plastic. The only way to get rid of the smell and the condensation was to re-wash, re-boil. I put the product in the dishwasher several times hoping it would reduce the plastic smell and tried the process again (several times). The results were exactly the same. So basically, whenever you feel like washing bottles, then sterilizing, then washing again, then boiling -then and only then should you use this ... product!
