This contained everything I needed and the bottles were so easy to use, once you worked out you didn't need to push the white section down, you just screwed it between the base and the main section.
These bottles are fab. And this set contains everything to get you started.
Also my baby started to notice the green shape and new quickly this meant food :)
The bottle cover was a bril bonus too.
When not microwaving, I used it as a drip stand for the cold water steriliser. :)
