I purchased this for my son along with the insulated pouch and sippy lid for toddlers. It was so flimsy that it dents at the mildest impact. It has a couple of rust stains inside which I discovered after washing and now begin to question if in fact they are 18/8 steel. The lids are bad quality too, not good for kids rough use. The sippy spout is of very poor quality and keeps loosing color ever time I rub it with my fingers. Bad customer services too .
