Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want the cleanest possible drink path, with bare stainless steel and silicone and no plastic at all
Independent non-toxic certification matters to you and you want it in writing, not just a brand claim
Your child is past the stage of mouthing and pulling at small parts
You want a bottle that comes fully apart so a straw never hides mold
You want your child's water touching only bare stainless steel, with no plastic lining inside the bottle
Your child is a toddler or older and past the stage of biting and pulling at small parts
You want a bottle that comes fully apart and goes in the dishwasher for easy daily cleaning
You want clean food-contact materials at one of the lowest prices in the category
The main thing to know
The straw and its inner tube pull out for cleaning, which also means small parts that a very young toddler could mouth or pull loose. This bottle fits a child past that stage best.
The silicone straw pulls out and is meant to be replaced over time, so this is a better fit for a child past the stage of chewing and tugging at small lid parts than for a baby.
Skip this if you...
Your child is a young toddler who still mouths and tugs at small parts
You need a bottle that keeps drinks cold, since this single-wall design is not insulated
You want the lightest possible bottle, as this one runs a little heavier empty
You are shopping on a tight budget and do not need the certification
Your child is a young baby who tends to bite and tug at removable straws
You need a full school day of water without refilling, since 9 ounces is small
You want a protective base boot, because this bare bottle will dent and rattle on hard floors
Neither of these quite what you're looking for?
