Cute, not the best

Difficult suction for toddler to sip out of. Also the straw melted in the dishwasher on one end.

Everyday cups for toddlers.

Great cup for kids. We use one for milk & one for water. Keeps drinks cold.

These leak like crazy. Out the side, out the straw. If your kids are like mine, and completely fail to set their cup upright often, then best of luck.

wouldn't recommend

cute and can keep drinks cold quite a while but straw leaks if tipped over and sometimes when moving it while it's upright. Big fan of zak products but let down by these.
