Leaked everywhere

I bought this as a easter gift for my son.I am so glad that his tumblers broke recently and we need to open it. We have had it a total of two days out of box and a month in the house , it did not fall it was not bitten. Yet it leaks absolutely everywhere. My son absolutely adores it , but the problem is is that if he knocks it over within the 30 seconds it's tipped it leaves a puddle as if he has just dumped it. At first I thought it was straw placement since he would try to take them apart. However even after checking and redoing it it still leaks. I might as well give him a open lid cup

AMAZING!!

I bought these cups hesitant, but for the price I gave it a try. They are leak proof!. my toddler has throw on the floor so many times... the straw is wide enough to be able to wash it (with a thin brush of course) AND it keeps drinks cold during this Texas weather. I am buying another set to have as a back up in case we loose them or forget them in places because life is like that with toddlers! give it a try!

Straws easily rip

Grey design but silicone straws rip from the top. Straws don’t appear durable.
