I bought this item for sterilising my breast pump, and use it on a daily basis.
Pros
-Very small so no storage issues
-Fast, no mess, easy
-Items can be stored in the bag following sterilising for use later in the day
-Items cool down quickly following sterilising, so breast pump can be used almost immediately
-Would be great to take on holiday
Cons
-Probably not cost effective if you need to sterilise more than once a day
-Noy suitable for sterlising a large number of items at once
Overall
Perfect for steriling breast pump and single bottle if you don't want to splash out on full size steriliser - highly recommend.
