Stainless Steel 10oz Drinking Tumblers + Food Storage

Lid pops off if dropped

I really wanted to like these cups, but the lid pops off if dropped. If it had better/more threads for the lid, then these would be the perfect cup. My toddler drop cups regularly. She's not even that rough with them, just normal accidental knocking it over and the lid will pop off the threads and spill everywhere. It happens often enough and it's very annoying.

Sturdy with a couple of issues.

I love that the cups are stainless steel with silicone covers; however, they’re not leak-proof if you have a child who likes to flip/toss cups. Our Contigo cups do not have this prb, but they’re shockingly not made for milk (despite being designed for CHILDREN). My son also figured out how to fully push the straw into the cup when the lid is on. It would be nice if there were 2 stoppers - one just above the lid and one below, so kids can’t push the straw into the cup. That’s definitely a flaw I hope can be fixed in the future…might require 2-piece straws or some other design fix that minimizes the mobility of the straw. (A change in the lid, perhaps?)

Not satisfied

I don’t think the size was accurate. I have the 8 ounce glass jars at home already and the 10 ounce stainless steel cups I ordered are the exact same size as the 8 ounce.
