This is a nifty little product. It saves space and is pretty easy to clean. I thought the grass world be more flexible (like silicone) but it isn't. This can make it a bit more difficult to push items into it. That being said, it also helps it keep items upright. It holds 6 bottles comfortably. I have only used it for baby bottles and small containers and it does the job nicely, keeping the baby's items separate after sterilisation.
