We started buying these when my oldest child stopped using sippy cups. These lids were a great solution to the kids being able to have a lid on the cups for in the car. The lids stay on very well. Even with drops never had one to come off. We also found out if your in a hurry and don't have time to run by local Sam's club these lids will also fit the Red Solo cups.

It’s was perfect for what I need.

Can used it with different cups

Stays on well and doesn’t leak

Do not fit sams 20 oz foam cups

Lids are great, never leak

Happy with purchase. Love using tbese with go cups.

So far many of the lids I have tried have been bent and cause spills.

Fast and Easy to pop on cup

Arrived in a timely manner. Can not be purchased in store.
