I purchased one of these microwave sterilisers some months before my baby was due and since we have had her have used it on a daily basis. The best thing about this product is the fact that it is really very easy to use. It just requires 200ml of water to be added before putting in the bottles/ breast pump or teats to be sterilised and then you just pop in into the microwave for 6 minutes and everything is ready. It takes quite a few bottles, teats, bottle tops and all the breast pump parts before becoming full. Despite this I find I am using it at least 3 times a day to keep up with the demands of feeding a hungry baby. One thing I would say, is its a little on the bulky side so do check it will fit your microwave before ordering, but if you are looking for a steriliser that’s easy to use and one that will save you time then this gets my vote on both counts.
