Query: best buy!

it's THE best item you can buy! practical, easy to carry, easy to store.maybe, it should come with 3 9oz bottles and 1 4oz, instead of 2 and 2; becuase babies rapidly start needing more and more...also all mags that come with these items are great, with great tips, some of them are not even included in m. stoppard's book! very useful.i STRONGLY recommend this item!
