Watch out for 'E' for error,
This review is from: Tomme Tippee Closer To Nature Microwave & Cold Water Steriliser (Baby Product)
When I first started expressing milk we used the steriliser a couple of times a day then when our baby could last a bit longer between feeds (if I cluster fed before leaving the house) we only used it once every couple of weeks and now we are weaning it is used daily.
We live in the South of England so brown build up occurs on the bottom tray, and below, very quickly and the bottom tray needs cleaned every few days.
My husband wanted to buy another model after we kept getting 'E' for error appear - this happened every 3 or 4 uses after a couple of weeks and is irritating if you leave the kitchen to attend to your baby only to find that it hasn't sterlilised and you need to start over again.
We also have the problem of it starting up again, without the button being pressed, when we close the lid after removing an item from inside.
You do have to be careful with the steam when you open it and i'm not a fan of so much condesation which means everything has to be dried before use but it does sterilise well as long as you make sure it starts up without any errors.
