I used only these the whole time my son used bottles and I really liked them. My son was formula fed so he used them alot. They are easier to clean then regular bottles and more sanitary I think. These bottles are durable. The liners are an extra cost but if you don't get the pre-formed ones and buy a store brand they are really cheap. They get less air than a regular bottle and need burped less because of it.
