We’ve ordered these a couple of times now, it’s great value for making the most of the bottles, of which we have two. It beats buying a new bottle each time a valve is bitten too hard or chewed. Ideally over time the child will learn not to bite the valve so hard, but that’s being hopeful :)
Make sure you order from a seller who can deliver quickly, ideally Amazon Australia, delivered to Sydney in a couple of days. The package fits in a standard letterbox.
Well worth it if you have invested in a Eddy or eddy kids water bottle this is about the 3rd time iv replaced bite valve on my kids eddy note o have 4 bottles on go two for daycare and home/bed also Amazon’s always seems to have stock of this as camelbak aus tends to always be sold out
